i agree: get the cheapie aluminized reflector from wally world for the front, get sides and rear tinted with UV resistant light smoke tint. i wouldn't tint the front because even the best aftermarket tint will eventually show small areas of degradation and it will be annoying on the front more than the sides and rear. also, it makes it more difficult to get the film buildup and smeariness off the front window (at night with headlights coming at you and when the sun is hitting you in the face). it also limits your choice of cleaners (no ammonia based cleaners usually dictated by film manufacturers).
i had excellent luck with the UV tint i put on my other car. it was designed by the same company that makes the tint for sky scraper windows. jensen, i think? anyway, it effectively blocked out the heat of the sun and made a huge difference while driving. i've had it on that car for over 12 years, and there is some minor bubling and it didn't really work out great visually over the defroster lines in the back glass, but overall it was very effective in blocking out the sun and UV. no fading or cracking and the interior on this vehicle is black.
