Don't buy a curved screen. Projectors are designed to focus on flat screens.
For the 'best' in affordable AT screens I would look at Seymour AV first. I think the SableFrame series is nice, but not up to the build quality of Seymour, and Seymour should do a better job with allowing audio to pass. You should also have space between a speaker and a traditional AT screen vs. a woven screen, so this may present an issue depending on how far behind the screen the speakers actually are.
For a projector...
CHEAP: BenQ HC2050
MID: Sony HW40ES or Epson 5030
IDEAL: JVC Home Theater Models - They all are great
In a good theater, the JVC projectors are really great models. They have, by far, the best black level performance of any projector on the market that I'm aware of. They aren't great with 3D or gaming, but are decent. They are quiet enough, and bright enough for a 135" screen.
The Sony is my favorite under $3,000 model. It can be had for about $2,000 regularly. It has good brightness, is very quiet, has great response time for gaming, and has good native contrast.
The Epson is not as quick as the Sony for gaming, but handles 3D better. The use of a dynamic iris means it can deliver better black levels under extreme conditions compared to the Sony, but I see when a dynamic iris is in use, so I hate them... So I prefer the Sony over the Epson. Still, the Epson is a solid model with the best zoom and lens shift on the market. A really stunning lens.
The BenQ is the entry level model to beat. The replacement for the W1070, they upgraded to an all glass lens and have reduced fan noise. Otherwise very similar to the venerable W1070. Under $1,000! Man, where were these 20 years ago?
