Just to let y'all know, I got my car tinted at the dealership, took 4 hours to do that and fix the stereo (turns itself down to avoid distortion), and it only cost me $140! Me and my stepmom are frequent visitors there, between my GTI and her Beetle, and apparently they're real cool, so they hooked me up.
And on a side note, they had a gorgeous '08 R32, but they wouldn't let me test drive it cause it was already sold :'( But I did get to sit in a showroom Toureg that was pimped out with 22's and all sorts of goodies O0
Blair's - http://www.textint.com/homepage.htm - i think they are up Central towards Richardson.
Also, dealer recommended Tritek, but haven't heard anything positive or negative about them. They are in Garland.
If you want perfection, then see Blair at Texas Window Tint in Dallas, near TI at Central and 635. Call 972-783-6005. He has done over ten of my vehicles and I've never had an issue, bubble, tear, haze, or B.S.
