I had reached out to him on March 3 for same reason (NGG).
It was impossible to reach on phone. Ended up having a brief conversation via SMS.
I agreed to PayPal him a refundable deposit of $300 to hold the game, pending hands-on inspection.
Note: Paypal account he had me send money to was Michael Freeman Michael4freeman@gmail.com
Pat Choy (Endless Pinball) finally made contact with him and arranged to visit the location and inspect the game.
Pat attempts to call him the morning of the inspection day and turns out the seller's phone is disconnected and he's not answering emails. I advised Pat not to go to an unknown location, to an unknown seller, with cash.
I've since initiated a dispute with PayPal over the $300 deposit.
How'd you fare?
