You say used like it's a slur. There are many fairly high quality bikes to be had used for a reasonable price in most areas of the us. With a few tools and a can-do attitude, you can make almost any bike fit for use. My current daily bike cost about $50. I replaced maybe $100 of bearings and other wear parts. Going on year 4 of medium use now; still works great.

Obviously not everyone wants a new hobby of fixing bikes. But its a great time for almost any hacker or maker.
