Thanks for the info guys. I'd like to have one someday and trying to get a good picture of them.

Are the handle arms easy to exchange on the machines? Could you set up your gear ratio and screw so that you could substitute different handles depending on the wood? Or is that variable not big enough without hitting your knuckles on your knees? Which one of the three Gabel mentioned is the best to change? Can you find the parts (if it not the handles)? Or are they usually ready to go for a 6'4 125lb man?
