Isn't there a larger potential "audience" on Ebay? Also, if one buys from one with a large number of positive feedback ratings ( smaller numbers can be "cooked" ), and uses the "Buyer Protection Plan", then one has some measure of protection. One can also use the escrow feature. All in all, I find Ebay a reasonable place to find some items, and to occasionally sell some as well. It's good to have some options, and all mentioned are certainly reasonable.
