Sold a Canon 70-200L f2.8 non-IS to Brhum (Brhum Bhatia), who could be the best buyer I ever dealt with. He only had a couple of posts and no feedback, but was patient and kind. He agreed to do a bank wire-transfer for extra security for me.
He researched in another forum the best way to ship to Canada, which I was unfamiliar with. And he even gave me tips on places to see on an upcoming trip I have to Canada.
Sellers, this guy can't be beat. He has little feedback, but take it from me that he's great to deal with!
