Pit bull does make a nice stand, however, there are lots of stands out there that are really nice and don't cost as much.
We have a guy that makes stands for us and they are super light and super durable. They are almost as expensive as pit bulls, but we like them. But, if someone was looking for stands, I'd really recommend looking at the new Vortex ones. They are super affordable (front and rear both) and are durable enough for racing, track days or street riders.
There are too many other good stabilizers out there with proven results...we have no experience with the pit bull stabilizer and haven't heard anything about them yet (good or bad)...so no comment at this time.
