I've used Hurricane Glass located on the Gulf Fwy to tint my old S10, my old Protege5, the Contour and the Tundra with no problems. I think I paid in the 120ish range for the Contour, but don't quote me. If you wait on the car, they'll be done a lot quicker than if you say you'll come back. They'll just push your car to the end of the line while they take care of the customers that are waiting. That happened when I took my Tundra at 9AM and didn't pick it up until almost 5PM when they called. By contrast, I waited on the Contour and they got started on it right away.

Hurricane Glass is off the Almeda/Shaver exit on I-45 South bound right off the feeder road. But, there are problem a hundred or so tint shops in Houston so I'm sure there's one closer to where you are.
