I am using an Elite 100" spectrum screen. Works great.
I also went ahead and got the bluetooth emitter kit from 3-d corp and it works AWESOME! I didn't want to say anything until I won the auction in case other people bid on it and until I reviewed it. I got the kit for $99 and it comes with 2 pro 5 glasses. The 3-d compared to the dlp link is night and day. No crosstalk and they stay perfectly in sync. I highly recommend them. My wife has a hard time seeing 3-d but with this kit, she saw it right away and was blown away. Thanks B15nut for suggesting them!
As far as a mount, I bought a cheap universal one on Amazon. (http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1
I hated it as for setting it up but once that's done, it's fine. Took some work getting the legs right and I had to invert them but it stays put. If you don't need to adjust it often, I would just get a cheap one.
