I'm really not a mooch

Tonya and I have decided that we really won't be able to exercise outside during the winter here in Indiana. We have subsequently been looking at exercise equipment for our home. Walmart has some good specials but everything is quite expensive. Does anyone have a treadmill or exercise bike they are not using that they would like to sell to us. We wouldn't mind paying something for one but we just don't want to spend hundreds of dollars for something. I know some of you have something that is collecting dust in your home or garage somewhere. Don't worry you don't even have to dust it off, we'll do that.
