Depends are where you are/tricky market. The college set want beaters cheap; kids want the frames (horz drops); and older folk are searching for their long gone youth rides. Breaing even is more the norm. If you already have bike flippers in your area/most of the yard sale bikes are scooped up. If you can find bikes $50 and under; lol. Have to love what you're doing/$ takes a back seat.
