I second and third the recommendation to go to a dealer for purchase. You'll get a warranty, help with the machine and most of all, it will have been serviced before being sold to you. You'll still get a decent price - don't be afraid to haggle - but you'll have peace of mind in case something goes wrong. Plus you'll have the opportunity to really try them out before purchasing.
I love Craigslist and Ebay, but our tendency is to panic about a deal getting away from us and we often rush into a purchase because of it.
Good luck.
