Has anyone tried 'Avenger' lnbf? I am curious if they're any better than JSC321. The price is the same.

No experience with this model, but it appears to just be another LNBF with doctored specifications. No such thing as a 0.1dB NR. Any LNBF with this claim catches my attention as suspect since the performance specification is already a lie....
I picked one up as a spare LNB. (Can't have enough on hand!). I can't say its better than the one I took off that I believe was supposedly rated 0.4db. It works ok but nothing I'd rush to buy.
It will probably function as any ordinary LNBF would, but, as Brian said, the mentioned specifications are not to be believed (or paid extra for).
I tested it yesterday. It's just as good as JSC321s with strong transponders, but it does better than JSSC321S with weak ones. On my VS Ultra box, there was about 5 point increase in signal quality on weak channels, and no noticeable difference on strong channels. Picture quality was the same.
I like it.
I like it.
While it may have slight improvements in some circumstances, I prefer the standard JSC-322 over the Avenger version, if not simply for the much better weatherproofing design on the sliding hood that covers the F-connector. The Avenger is not as ruggedly built, in my humble opinion, will not do as well long term against the elements of rain and sun. I have no complaints with the standard JSC-322's performance, so why argue with success?

Totally agree. I was suprised it didn't arrive with the sliding hood to cover the F-connector. Now that it's skewed 25 degrees, there's nothing to keep the rain from getting inside. I'll get my glue gun this weekend and fill it up 
Update.. after a few days in the sun and 100 degree heat, it not performing well anymore. I started getting 'searching for signal' on many channels. All other channels showed degraded signal quality. I checked everything, the dish was aligned ok, all connections were tight. As soon as I replaced it back with JSC231, the problems went away.. disappointed. It didn't even rain, so it couldn't have been water damage.
Please clarify your comment. Are you saying that it is technically impossible to achieve 0.1dB NR, or that it would make no apparent noticeable improvement even if you could since other factors are more or equally as important? Is it possible that the 0.1dB is accurate but only for a given frequency or narrow range of frequencies as HF antennas can have a low SWR but not have it low across an entire band? I want to find the best LNB with capability for absolute best performance at receiving weak signals. I'm not so concerned about other practicalities like weatherproofing, physical strength, etc. I had thought the Avenger and Spitfire were among those good in this way, but I am not hooked at the navel yet to any LNB: just want to find the best. I don't want another universal; I'm just looking for the best standard linear one can buy.
I’m using two of the Avenger on my Prodelin dishes and they seem to work OK, but I probably won’t buy anymore as I purchased a Xtreme II LNBF and I like the way it’s build as its all metal construction and fits the holders that I’m using better, so when needed I'll most likely buy more of these. And best of all it’s easier to get to the connector when installing or removing a cable as the Avenger hides part of it and you could have problems removing a cable, been down that road already as it cost me one of my original three Avenger that I had.

If you look at them you'll see that the housing comes down over part of the connector so you can't get to the nut part of the connector in case you over tighten the cable. That what happen to me as I put on a small section so I can hook up my FS1 and when done us a barrel connector. When I was hooking up my meter I didn't realize that the cable was also turning and it may have tighten itself or when they build the LNB they didn't really tighten it before attaching the the board as it took very little to destroy it and I only finger tighten.
I purchase from Ebay (330551320886) for 8.99 and free shipping for the Xtreme II.

I can assure you that the 0.1dB NR is not obtained on any frequency with this or any other "off-the-shelf" LNBF. This is only marketing BS! On a line selected and optimized LNBF it is probable to find a percentage that maintains a reduced noise figure and gain characteristics, but it will unlikely to be below a .3 or .4. Uniform gain, phase isolation, stability at operational temperature along with other electrical and design considerations are more of a factor in operational advantages than the NR.
You will not find uniform performance between LNBFs that are simply mass produced and unsorted. The main difference between a higher priced LNB and a lower cost unit is component choice along with the sorting and optimization by the manufacturer.
This is all good to know. But this situation creates a dilemma for consumers. It is usually not a wise policy, in general, simply to buy a more expensive product. More expensive often doesn't necessarily result in better products. If we can't trust technical specifications, and we know we can't trust what salesmen say, then where do we turn? I turn to listening to what actual users of a product give in feedback after personally using a product. And so I am reading what actual users are reporting on this and other forums. Although I rely even more heavily on reading carefully done comparisons of similar products in actual field testing by an organization I trust. It would be good if companies such as yours could do trials in real world conditions comparing different models of satellite related equipment and publishing these results.
Agreed.... you are on a great resource for and will find numerous test results done by SatelliteGuys on many of these LNBFs including several by myself.
Personally, I would believe a real life test posted and confirmed by several sources over one that is provided by a distributor or reseller. Satellite AV product promotion and specifications are based on conservative product expectations, but unfortunately this approach isn't always typical in this market.
Of course, your mileage will vary as the batch variations, supporting hardware, signal footprints and local terrestrial noise will provide different results with seemingly identical gear.
