My experiences in the spam section have all been good.
I've had people hold stuff with and without deposits, have held stuff with and without deposits.
I held the Hydro for 3 weeks with no deposit and the guy showed up on time with cash.
(That was a verbal handshake over the phone)
I sold boats, boat stuff, stereo stuff, etc. without a hitch.
Hell, even Homez and I had a smooth transaction!

Everybody I've dealt with has been good to their word, and I have tried to make a point of returning that.
I make a point of cutting a finders fee for any help selling stuff also.
Pay Pal, Checks, cash, all have worked.
I have bought stuff that was not exactly as represented, won't post details, but nothing that warranted any bitching really.
This is always the first place I look when buying or selling most anything.
