Eyepiece for a 20D

[Typhon]

I managed to lose the eyepiece to my 20D at Silverstone a few months back and could really do with a new one before next Thursday. Does anyone know of somewhere that sells this item? I tried Jacobs and LCE and they both could take up to two weeks to order one on, which might be too late. Couldn't find much on ebay or amazon either. Is there anywhere that sells this, or is there a good 3rd party item that I could get that will do the job?

Edit: took another look, looks like i found what i wanted, although there's no mention of what cameras it fits
