So have I. But that market is rather limited in the number available as well as noticeable price hikes too with more desperate/bargain hunting people hunting for any sort of bicycle (or anything else for that matter) due to the new bicycle boom or craze right now. Prices are going up rather quickly there too assuming you can find the bike/other product you want. The prices will probably drop again when the economic hard times actually pick up to pre-recession levels again.

As late as a decade ago, I was able to buy used bicycles or other things at a decent prices. Not anymore.
