I recommend Quality Bumper in Mesa.
You can see their handywork on my RS if you make it to any of the meets. They pretty did good work, including doing the rear window in one piece for me. There are a few tiny bubbles if you look close, but they'd probably redo those windows if I took it back to them.
However, I have one warning. They're not cheap. (Unless you've got a bunch of really good friends who get together and buy you a really nice birthday present.
BTW: I wouldn't trust Thomas Motors as far as I could throw them either.
