question, are you sure the unit is running 81.5 avg? with standard settings, it normally averages 82-85.
Shipping+escrow included?
It was summer when the overclocking firmware became available, and so I've not been running them at a permanent ~350 MHz chip clock, it would have been slightly too much fan noise.
Shipping included (assuming the price isn't too much of a "surprise"), and as far as escrow goes, I've not sought it. If the buyer can find an escrow I deem trustworthy, I'd be happy to use them (John K. is so obvious, but I don't want to have to be the n millionth person contacting him saying "we've not spoke before, will you be my escrowwww?"). Other wise, it's payment first and I'm the escrow (as per conditions in the OP)
