Changing "Gears"

I've decided that I really want to get rid of my treadmill and get an elliptical trainer. I was holding onto the mill because I swore I'd use it but I think I know better. I thought I was smart in buying a manual one because logic made me think that I would burn more calories by making the thing go myself. I wouldn't know now though because the wire to the meter broke so I have no idea what I'm doing besides how long I've been on it. LOL At least I can say that it served its purpose and I did get use out of it for the price that I paid. Hopefully I can get an elliptical soon, I've always wanted one.
