A guy in my club bought one of those NoMars at the International show last year.
He seems to like it.
I did ask them to demo changing a 240 on a shaft wheel and they had one there and did it with what appeared to be ease.
Price wasn't bad but I had a feeling that I could easily break it. if I were going to do it, I'd go ahead and shell out the $2,800 for a machine so I can easily change tires on anything, even friends and neighbors rigs.
