I hear Pitbull is generally regarded as the best, for quality and features.
I also hear that T-Rex is comparable in quality, and can be had for cheaper.
you've heard mixed stories.
Pitbull is the best for sure, but trex does not stand even in the same building let alone zipcode as pitbull.
it works fine for normal use. But if you work on a couple bikes or just use it very often, it rusts and requires red loctite if you are going to be banging it around.
