I bought one about two years ago. To be honest, I don't use it that often because it seems like the time just drags on and on when I'm on it. Being that I hate exercising to begin with, dragging time only makes things worse. Unless you can put it in a room with a TV (unfortunately, I cannot), I would recommend just walk/run outside. The down side to that, of course, is that you cannot count calories burned, distance, etc.

I think I would probably either buy mine on sale, or buy it used. It's an awful lot of money if you don't use it often.
