I bought an Atlas TC211 a few years ago from Greg Smith Equipment. Now it's the TC221.
It is awesome. No regrets whatsoever. I charge my friends $10 a wheel to mount and balance tires for them. The machine has over half paid for itself, just from that. Not even counting how much I've saved on my own tire changes.
I've changed sportbike tires, 21" dirtbike tires. I even changed the tires on my 20" truck wheels.
I looked at No-mar before I got this one and decided it was worth the extra money. Now, 5 years or so later, I still feel the same way.
