RE: OT PAYPAL
I have heard of a couple of people who have been burned through paypal by having their funds refunded. Only way around that is by not keeping a balance in the account. But there are certainly ways to be burned on either end.
I have had to collect a couple of times on non delivery of goods. Paypal refunds a portion of the amount (never had a full refund) so I then use my Credit card to collect the balance from paypal.
As a rule I feel more secure as a buyer than a seller dealing through paypal but I prefer it 10:1 over Money order etc.
Just be sure to use a delivery confirmation on the item - cheap insurance to prove you shipped the item.
