You said fixed frame? If you're a bit handy at all, you should look at a sheet of 4X8 wilsonart designer white formica (it works out to be about 104" diagonal). You can then simply build a felted frame around it (the "if you're a bit handy" part). The wilsonart is $42 at home depot/. The felted frame cost about $40 to build. $82 for a screen that produces an image better than five of the six samples I've gotten from different companies, and as good as the sixth. I didn't even use the "designer white" as everyone says, as I thought this, now permanent screen, was going to be a temporary thing. I'll only replace it for one reason at this point: If I decide to hang a TV on the wall and get a motorized screen.
There are a few perks about the wilsonart that I have noticed. First, you don't have to be super delicate with it and it's not easy to damage (great if you have kids). Second, it's easy to clean if something does get on it (it's a countertoop afterall). Third, it provides a great image for a very little amount of money. So, if it was damaged somehow... it'd only cost you a trip to the home depot and $42 to fix.. instead of another $700-$2500.
Now, if you can justify $600 to buy an Elite screen over the wilsonart, you might as well justify the $2500 and get the SI Black diamond. At least the black diamond with provide you with a noticeable benefit (ie, it's ambient light performance) over the wilsonart, where the elite might not.
