I love Peugeots, but would hesitate to get one because of their "French Threads" which are a slightly different pitch than others. That makes it harder to find parts that will fit. Japanese makes and Chinese made ones should have more universal components.

Don't forget estate sales. There tend to be more old bikes that weren't too abused or used. Estate sales are better than garage sales, because at garage sales, people select their unwanted items. Estate sales have a wider selection.
