I see that the thread is now closed, but I would like to report the status of the transaction in case you would like to update the thread.
The purchase was made by roughly half btc and half in the form of a check (business check, if it matters). The laptop was sent UPS with insurance.
No escrow was done, but signatures were required by the receiving party for both the check and the laptop.
The btc was sent immediately and the check was received a few days ago and deposited. I received the laptop today, sealed and brand new. Exactly what I expected to see.
It was a great transaction overall, and I hope that gpatt will agree with me.
