Has anyone ever used the Tenhulzen Automotive 4-Wheel Alignment System, looking for any feedback in quality, easy to used and accuracy.

anyone? local alignment shops suck and have said foreign car alignments are a "nightmare" give me a break, rear camber, then rear toe, then front toe

Does these (4 wheel versions) work on anything but an extremely flat surface?

I have a Porsche focused race shop close to me that charges $280 for an alignment.
I have a Miata focused race shop close to me that charges $80 for an alignment, and encourages me to sit in the car and talk to the tech while it's being done. The tech is also a racer.

So, look for a race shop that focuses on Miata's, those guys are, um, cost sensitive.
