I've been thinking I should buy some sort of indoor exercise equipment. I guess I'm leaning towards an "upright" stationary bicycle but I also see recumbent bicycles and some sort of eliptical stepping thing.

Anybody have any experience with these types of things?
1) Types of indoor equipment.
2) Brands.
3) Features.

Thanks
