Anyone know of a good place for a body harness? I want a quality but cheap one (if thats possible). I know Ironmind.com had one, but its far to expenisve, at least for my needs. Im not going to be pulling cars or anything. I need it for A, my sled and B, I want to do those sprint starts (ie 300 workout video) and similar stuff (ie band bear crawls like in the Sean Sherk Caveman video).
