This T7 para is looking for a way to get some exercise and this looks like fun. The problem is how do you know which make is the best for me?

I can't transfer far, which would take out the low riders. I need to be able to try one out for a week to see if I can endure the excerise on my shoulders. I have had them both replaced, so don't want to fork out $1,400 and realize it is too hard on the joints.

Any suggestions would be greatly appreciated. I live in S.W. Lower Michigan.
