I have bought and sold several bikes, components, and other stuff on Craig's list. Although you will get some idiots just like any garage sale/paper add, people will low ball, no show, and the like. I have actually made money on bikes using Craig's list, but eBay has mostly been a loser. Last bike I sold on eBay to a local buyer, the idiot called 2 weeks later saying it needed a $100 repair and he wanted me to split the cost. this after fully inspecting the bike and the listing stating no refunds, he left me negative feedback overstating the repair cost by double and of course not mentioning the fact he had the bike for 2 full weeks before calling to try and extort money from me while threatening bad feedback. Of course I left positive feedback right away when he picked up the bike like an idiot...
