We are contemplating a treadmill or elliptical for the basement for the winter. I plan on buying off Craigslist, can't afford new and would like something decent quality. I am used to gym treadmills and ellipticals, so I think a cheapo would just be frustrating, but I don't think I can afford gym level. We are willing to pay for quality, but I see a gym-level one (Matrix T5X) for $2500 on Craigslist that was $4500 new, and that just seems crazy.
How did you choose what you have? What brand/model?
