also check out youtube for some video of it working on other cars. It's a pretty sweet setup but more involved than I'd like to get on a car I'm not going to have that long. If my car was a keeper, then I'd definately consider it.

Also, yes, you can make one from scratch and it's not that hard using the info off the net. But, I'd almost like to pay more as a tradeoff for some tech support while installing.
