david136 is a scammer
Responded to my wanted ad saying I should contact so-and-so as he's got one for sale.
Decided to string him along.
Sent me photos of a helicopter engine probably worth half a million dollars offering it to me for $1500 and postage to Australia would be $100, for a 200kg engine!
The said he's having trouble with his paypal account...but I can send cash using some other methods he gave me, obviously with no buyer protection.
