I really appreciate all of your help. I had no idea it would be so hard to find good parts - well I had some idea which is why I posted this here. I'm still open to suggestions. Thanks to everyone.
Its much easierto ask for forgiveness that to ask for permission. Get a 10 footer, a six foot dish won't get you nearly as much.I'm doing my best at selling the concept of a 7.5, a 10 footer would not fly. I just found another perfect dish on the Res, though only a 6 ft.
I was under the impression that on the Asian superjack actuators the one with the oval rod end was the standard duty version & the one with the straight clevis end was the heavy duty version. on teks website they say its a "heavy duty" superjack. so if i'm correct either their picture is wrong or the description is.The Von Weise works out to about $400 CDN, so I'm looking for something else.
In Canada the options seem to be:

or
http://www.tek2000.com/cgi-bin/web.cgi?command=product&item=24-inch Linear SuperJack Actuator-ND
So doesn't seem to be much else on ebay either...
Qarl actuators are GARBAGE Chinese Superjack clones. I had one for my 6 foot dish, and I wouldn't dare use it for anything larger if you are in any area of winds. One good wind storm and your dish and actuator is history. I've seen people post photos of them bent in half.
Ebay used to sell them for $40 U.S.
