dont trust ebay compatabilty lists! :x
'it`s best to identify the part you want to replace and a quick ask will set you off on the right track. (it will on this forum anyhow)
Look on the bright side, if his listing is wrong, he is at fault, so you are due a refund (make him pay return p&p).
If he refuses, open a case, it`s surprising how ebay traders react, especially if theyre wrong.
