Tint Suggestions?

I'm looking to get some window tint put on the tib. The situation is that i'm in jersey, and front window tint's completely illegal. What do you guys suggest? A light, even tint all around? Would a semi-dark tint on the back and none on the front look funny? i don't want to blow money on tint that is barely noticeable/useful, but i also don't want a bunch of tickets or a jerk cop ripping it off my car. I've heard the "get an eye doctor's note thing" and about the factory stickers and what not, but that doesn't seem to realistic to me. maybe someone from the area can help me out with some advice here.

Also, what is a fair price to pay for installing tints? A quote on my old tib seemed expensive for such small amount of glass on the car, maybe it was the back window?

thanks for any input.
