Tinting - what's the difference ?

[mazdaagain]

I'm getting my car tinted but am a bit confused about the difference in the cost and quality of tinting.

The most recommended shop is FX Auto - $250 tax in but I have seen Noble Tint at $180 + tax and Audio Heaven at $199 + tax. Is there a difference in the quality of the materials or is it strictly workmanship ?

FX Auto says 3 hours to do the job and Noble says 1.5 hours. Is this a difference in quality of labour ?

Any help would be appreciated.

I've had my last 3 cars done at FX, so I can only really comment on them. Here's what I really like about their work:

1) All cutting done on computer controlled plotters. Nice clean cuts.
2) A+ workmanship. Lifetime warranty on the work, and I've had to go back once with no issues whatsover.
3) Place is right near a mall, so you at least have something to do while you're waiting :)
