As an alternative, you can have the guy send you a personal check.
Then go to the guy's bank and then cash the check.
If you decide to go the deposit route, you can hold the machine until the check clears.
An easy way to verify that the check has cleared is to ask for a digital copy of the cleared check.
When you deposit into your account, place a unique symbol or message on the check. When the digital image is sent to you, verify that your symbol or message is on the check.
Once verified, you can set start the shipping process.
While personal checks are "old school", you can still safely cash them as long as both you and the buyer are willing to work together.
As for Paypal Gift, my understanding is that a gift cannot be disputed. Once sent, he would have to prove that someone other than him sent the gift and that fraud is involved.
In any event, please good luck with your sale! Tron LE is awesome, but $11,000 is even more awesome!
