We used Quality at work all the time since they are next door. I also used a place called accurate window tinting right down the street. I think that guy is the shit. Faster turn around time, cheaper, explains and shows why he is better, lifetime warranty and is all around a great shop.
He is always busy but usually puts our cars through quicker than Quality. Also he runs the shop himself so he doesnt work an 8-5 schedule. If you want John I can IM you his number and you can tell him Clark told you to call. maybe even get it in quicker and cheaper. Just a thought.
