I have a real cheap model and always wish that we had gotten a better one. Ours doesn't work very smoothly. If they have them set up in the store then make sure you try them out and pick the one that works the smoothest and feels the best to you. If you don't like it you won't use it. I also wish that ours had a built-in pedometer so I'd know how far I've walked.
This is a great questioin. I've been wanting to get a treadmill too...does anyone have a manual one? I'd love to get one like at the gym, but I know they can be very expensive!
