Your price range kind of limits it unless you build them yourself. One of the guys on our site did that and they work really well for his Cobra and Corvette. I have a low ceiling so I got the Kwik Ramps and really like them. I just put a line of aluminum tape along the drivers side ramp to line my back wheel up with when I am backing on and a cross piece at the place I want to stop and have never had a problem. But they cost a lot more than $100 dollars. I will go to our site and see if I can locate the thread where he built his and he has pictures and step by step instructions on them, plus you can change the height when you build them. The Kwik Ramps that I have are 20 1/2" high when jacked up and then the height of the car on top of that makes it easy to sit up in most places.
EDIT: OK, I found the thread where he gives the instructions and pictures of the way he built his ramps. Also Dean, who posts in the thread built a set a little different but you can look at them if you want and maybe get some ideas.
