I've bought & sold some items from DVInfo.net & DVXUser.com & only had good experiences.
But it has been years since I've really had a bad experience on eBay as a buyer, as a seller I've had some head aches (PayPal nearly always sides with the buyer these days, no matter the amount of stupidity).
I've even had some good luck on Craigslist in person & across state lines.
Of course with all of these I have my paranoid scammer BS radar set to maximum sensitivity, so I just I quickly & silently walk away when I start hearing some beeping going off.
