I am not telling you that you should buy from them but I am a satisfied costumer. I got my dish delivered within 5 days after placing order. I had minimum damage with the shipment. It did not affect the dish performance.
Yes, I got an 8' from them (wish I'd got the 10' but resources didn't allow
). Delivery was fast (some minor damage to edge of the mesh on a few panels which was easily tapped flat). We have been using it for almost a year now and it has held up well so far. Is it the best dish out there, no, but at the cost for what you get it was a reasonable compromise for me. There are of course used dishes out there, many of which were built very well and would serve someone who aquired one for many years to come. DH is a company that still sells new high-end dishes, as was mentioned here by Titanium, but they are definitely out of my price range. If cost is not an issue then check them out, otherwise, get the nicest dish you can find (used or new), then relax and enjoy the hobby. 
What Primestar dish are you referring to? I don't see anything but generic steel ku dishes on their website. Link to product?
It's listed on their website for $129 + $100 shipping. Also on ebay from Satellites Galore (http://www.ebay.com/itm/120cm-Ku-Band-Solid-Offset-Satellite-Dish-/331377108934) for same. One person reviewed it on ebay and seemed to be pleased. Looks like with Amazon you are still paying for the dish & shipping + an extra $19.49 tacked on as well.
No not all offset dishes are Primestars. There are many different manufacturers of offset dishes.
That and with the disappearance of the combo C/Ku LNBFs the handwriting is on the wall!
