members with no feedback?

If you are the seller there is very little to be concerned about. If you are the buyer you can ask the seller if they have feedback elsewhere (like Ebay). I've bought from individuals that had substantial good feedback on Ebay, but little or no feedback here. I've also heard of COD (cash on delivery) payment. and using escrow, but have no experience with either. Short of this, I'd move on.

While I have spoken on the phone on some transactions, I find phone conversations a bit sketchy. 99% of my transactions (and I've had a number of them) have been without phone conversations, 1% with phone conversations. Too often, I'm afraid the folks I've spoken to I'd rather not have spoken to. (some strange folks out there!) But if you are buying from a person w/o feedback you're sort of stuck with the need to establish their credibility as a legitimate seller.

Good points Justlisten. I do the things you mentioned too. I probably should have said there is less to be concerned with as a seller than a buyer. That chargeback 2 months after the sale from Paypal seems like something that you could have taken to litigation.
