window tinting

Does anybody know what the best window tint is, I live in Florida and it just has to be done, I am not crazy about the idea but as I said it is almost required, I don't want it to look like a limo just keep out some of the damaging rays.. By the way I HIGHLY recommend a front windsheild sunshade, it is made by covercraft the guys that make car covers, it is custom made for the car, and fits like a glove, ( about $75) and worth every penny, if your car ever sits outside, i.e work, etc
