Aftermarket fuel caps

I'm after an alloy cap for a ZXR750 M race bike, had a bit of a look online but didn't see a whole lot - anybody put one on and can recommend a brand / source??

I got one from a guy on eBay USA called gas cap guy or something like that.
Kaneg does them and he's a site sponsor too!

Thanks Jim,

If you make it out to Eastern Creek for the Bary Sheene in March I might bring my ZXR

Will stick a pin in that date then!
