Very strange
I've dealt with him a couple of times, with large sums of money and had no problems. Seemed like an honest and genuine guy.
He did go a bit quiet at one time recently due to a family crisis so keep that in mind. There could be a genuine reason. Very strange that someone would honour expensive items then run off with a few quid, no?
He is ebays "faitti" right? (Just to be sure we're talking about the same guy)

Honestly, he seemed like a top bloke to me. Is Zaki around? because he knows him.
Actually, I remember ebay member "brennyboyuk" dealing with his stuff the last time he was offline and i've just looked at his feedback - 2 recent negs for very small amounts. Odd.
