1) Send cash by certified check or money order. Send it priority so the seller knows you're serious. Paypal's ok but it can be another whole layer of BS. The whole Ebay/Paypal world is a sordid mess.
2) Receive merchandise
I've had dozens of transactions here and A-gon and only one seller was a PITA, and only one piece got trashed by shipper.
Know this, this is the world of second hand and the honor system. At some point,you will be dissapointed in the condition or performance of a piece that you buy and you also may well get totally f****d at some point.
It's like the stock market, go there with discretionary cash that you're willing and able to lose.
Your best option is to buy close enough to pick up, or of course, buy new.
