I am finally ready to announce http://www.dogeslist.org! It's a marketplace to buy and sell anything for doge, which might not be too special, but it does offer ebay-like payment processing. So you're not handing over your hard-earned coins directly to the seller, it will be kept by us for a while until you received your item.
I can imagine it if you are a little sceptical about the concept, so then just try it out with a few smaller amounts, for example by posting a listing yourself and paying to yourself, to see how and if it works. Hopefully that will give you a bit more trust and confidence!
