possible ebay scam?

[Big G]

Started talking to a guy selling some RC gear who was in spain selling on ebay.

The item got relisted because he forgot to put a reserve on and sat there for a few days with no bids. so I messaged him about a possible buy it now (like you do) and got some better pics showing the condition and how long he'd had the item, etc,etc. the usually stuff.

The guy wanted £55 for the item which he said the reserve was and wanted to keep the transaction through ebay which was fair enough. he told he's get a quote to the UK which turned out to be £10 rather than £5. Since it was from spain I didn't think this was much of a problem. he said bid £60 which would include the £5 listed P&P and make the whole deal £65 which I agreed with. After I bid it jumped to £50 which was actually the reserve so I told him I would send him the extra £10 straight after the sale to make it up and he gave me a paypal address to pay.

The strange part being the paypal address given by ebay to pay differs from the one he gave me to send the £10 to. This morning I get a message saying he got the £10, but no sign of the £55. Paypal are showing this

28 Oct 2009 Gift For R F Completed Details -£10.00 GBP
28 Oct 2009 Payment To different [email protected] Unclaimed Details Cancel -£55.00 GBP
(name and email changed. dunno if I should publish those)

Worst case I loose £10 since ebay will cover me on the other £55. The unclaimed bit is a bit strange. Obviously I won't send the £55 if he asks me to send it to the other address as this won't be protected.

What do you think?
