I've stopped selling high (and low) priced goods on mafiaBay because of all the nigerian scammers, double dipping with (notyour)PayPal, idiot buyers who want you to bend backwards for them and still leave (-) feedback because they can't read the auction, oh and the fact that after paypal is finish double dipping they can (and will) use your cash as an interest free loan until they don't need it anymore.
Craigslist doesn't get me as many bites as it used to, and most of the time I get e-mail and phone taggers who want to ask questions but don't really want to buy.
I don't think you'd be able to sell on AZ unless there is some sort of auction area. Isn't technology one of those restricted items?
