Car Window Tint Project

I have a new to me used vehicle that I would like to add window tinting to in the back. I know that there are tons of different kits out there that I can choose from, but I know that some of the tint kits really don't come out looking all that great even if someone is good at applying it. Is there a good car window tint out there that is fool proof for someone who may have never put any on a vehicle before. I have a pretty decent budget to spend on it, however I do not want to spend the money to have someone install it for me. Check out Austin window tint.
