Korg Mono/Poly

Just got a mono/poly and am I amazed by the organic and liquid sounds
I get out of it. This synth is way more interesting to me than a
Minimoog or Jupiter or MS-20 for that matter and for a fraction of the
price.

My MP is in good shape but unfortunately one of the keybaord keys is
cracked. Anyone know where I can get a new one?  Are they a standard
size/type that I can order from a generic parts supplier?

thanks,
