I've never been spinning, so I don't know much about it, but I saw this on craigslist. I did a search and it looks like Schwinn spin bikes that list for over $1000. I'm not interested in it myself, but just in case someone in the St. Louis area is interested! It doesn't seem like I've ever seen a spin bike advertised.
