Cate's sounds identical to the one I purchased (except for the brakes), but mine was a reconditioned rental once, hence the price difference. I like the sound of the brakes on the handle, though. The foot operated one can be a bit of a pain when you're in close quarters, like getting into a car. I bought mine from fred walton, but I'm sure there are other sources. Don't forget, you can aslo get them from the red cross on long term loan.
