I guy a used to know in Oklahoma said the best window tint he ever had done was done by a shop in the springs. Don't know the name though, sorry. FWIW, mine was done by 'Denver Window Tint' on Parker road and Iliff. Its been on for about a year now and haven't had any problems with it. Only cost about $1500. HTH.

Edit:
Whoooops!! $1500

That should read $150. Sorry. :p
