Ah well, you can't do much else in that situation Rich 'cept go down the 'legal' route!

Have you tried emailing them through eBay, as eBay have altered their website about a week ago so you can do that and keep a copy of what you send to other members in your Messages page?
Might be worth one last try to see if he responds and it also means you have something logged through eBay should they have to get involved in the transaction to recover your money.
Good luck with it and please let us know how you get on.
