Buyer pays paypal costs

And now the fine print:

The Gabriel DeLeon rule: You can audition the unit at my place. Once you buy it it's yours, as it comes with no express or implied warranty of any kind.

The Franz rule: By buying this unit you acknowledge that you hereby waive any protection plan that is offered by your payment service that exceeds the 48 hours you have to report any issues with the unit. So if for example you choose to pay by Paypal and the unit fails 40 days after you bought it, you hereby agree that you will not use Paypal Protection to get a refund from me.

Have been on Audiogon for a while, but Gabriel and Franz forced me to add some fine print.
