oddiofyl, you assert: "So many Pay Pal scammers." I suspect you haven't had any real experience. I've sold hundreds of luxury items through Audiogon and my own website and my preferred payment method is PayPal since, unlike credit cards, they associate a bank account with a "confirmed" shipping address for which they promise seller protection. I've never been burned using a PayPal transaction. I can't say the same for credit cards.
Perhaps the increase in price perceptions is due to the fact that there are now many dealers offering trade-in and demo items for sale?
