Unfortunately, I don't know if there really is a great way to deal with crappy situations like this. Where do you draw the line? I have posted fewer than 50 times because I am pretty much a lurker here since I operate under the assumption that most of the people on here know much more than me. I expect that many of the sellers on here are first time sellers because they don't need some gear they have sitting around, not that they are trying to make a living selling on dvxuser. In that case, having a specialized ebay-style marketplace might have the reverse effect by attracting even more scam artists. So far my plan has been to only buy smaller items or talk to the seller over the phone, and I pay using PayPal, so if it is a scam I have some way of trying to get my money back. I'm not sure those are great solutions, but I'm equally unsure that there is really any good way to completely prevent things like this from happening.
