I believe there is a pretty extensive thread/sticky on this topic.

But...I'd recommend Thee Tint Shop on Busch Blvd. I am super anal retentive when it comes to tint and Shane is the only person who I will let touch my cars. He is a great guy who does super high quality tint work. His schedule can be a bit rough and sometimes the next appointment may be a few weeks away, but he is well worth the wait.
