I ended up going to Mister Tint in San Jose because of Yelp reviews and because it was convenient enough to drop it off during work and pick up later; much more expensive though. I also didn't want my door panels removed like they do at Best Image. My good friend just went to best Image 2 weeks ago and is happy with his tint: $150 for everything save the windshield on a Civic. I've seen it and it looks fine; very good value IMO.
I was going through a thread and saw your post about best image. Did you end up getting your tint there? Everyone in my family has gone there and love it. But I've been looking through yelp and I'm not sure..
Personally, I'm not sure if it's worth how much I paid at the dealer, although I am glad I did because the radio sucks for the most part; but I qualify that with the convenience of having a dedicated ipod in there. If I currently didn't have one I would just buy the one from MazdaParts and install myself since it comes with instructions (I think). If you are hesitant you can see if a local forum member with experience opening up the insides is willing to help or just wait until someone posts a how-to.
