Battery for AV500 60gb model

[Bulletguy]

Hi

I have an AV500 60gb model which takes the battery type s/n 400099 but am struggling to find a source for a replacement battery. I found one on ebay but the seller is asking £100 !!! That seems pretty excessive to me.

I am in UK and have searched Google without luck. Any help appreciated.
