I'd say your safest bet is to buy through someone reputable, regardless of the payment method, you should be looking to avoid scammers first, payment method second. It's not the payment method that's going to steal your money, it's the seller.
PS. PayPal is not the best way to pay and stay safe; I've been hosed by them both buying and selling. I've never been screwed by someone reputable.
