I just don't understand how some people get so emotional over a simple business transaction. Craigslist is full of self appointed free market police, on both the buying and selling side. I think it's hard for some to understand that sometimes people just want to sell something, and really don't care what affect it has on your obsessive bike hobby lol
I do like the Farm & Garden section though. Lots of good deals to be had, and I have yet to run accross someone as nutty as the bike folks
