So far I've had good results with Craig's and with Armslist, but it always pays to cover your assets, and use your head.
A sure way to get get burned is to go there with a big case of "I Gotta Have It!"
CYA and do your home work and demand face to face transactions, or forget it!
Forget personal checks too! Just way too many scammers have found out there are ways to skin the gullible.
So use your head and be careful.
That will be $.50 for the advice because if it's free you get what you pay for!
