I have been told by a few people that Tropical is good. I cannot give you a personal review though, sorry.
If it is run by the same guys who run IMG (the body/mechanic shop that surrounds Tropical) they should be good.
I have had a few dealings with IMG (some mechanic work on my car and my dads SUV .. as well as rebuilding 2 Classic cars for my dads boss) and they did a great job. So if its the same people then you should have no problems.
If you decide to use them, update this thread about them. Actually post a review if you can on whatever Tint Shop you choose in the NJ Shop review forum.
I am going to be looking into tinting my care (whenever I get it back)
