I got them from the Toolwarehouse

Here's a direct link to the Go-Jaks
http://www.thetoolwarehouse.net/shop/MAN26.html
The 5000 are currently $263.95 and the 6200 are $375.75. The Toolwarehouse has the best prices on the Go-Jaks from any place I've found so far. I've ordered other tools from them too and have never had any problems with them. They are in New Jersey. The Go-Jaks were shipped with UPS.
I have the 6200 since I've used them on my 1987 Chevy Caprice wagon also. The 5000 are more than enough to support a Mustang though and if that's the heaviest vehicle you plan on picking up then there's no reason to go with the 6200.
