Advice on buying a new ibook battery

[allan_zip]

I need a new battery for my 12" 600mhz ibook (late 2001 model). Can anyone recommend a good place to buy in the U.K.
There seem to be a lot on ebay for about half the price that apple sell theirs, i'm tempted as i'm not sure if the latest batteries apple sell are even compatible with my ibook.
Anyone have any good advice on a deal they got?

i would stick to apples 12.1 ibook Batt IMO

£88.99 is expensive though but i would stick with it
