I have a Famicom, but the attached Controller I is just not very responsive. The carbon on some of the contacts has really worn down. I would like to try a replacement. I do not need NOS, but I do need one without a totally obliterated faceplate and with original pads that are not cracked or worn out.
I have some spares. They're not in perfect condition cosmetically, but not that bad and the controls still work OK. PM me your address if you're interested, you can have one for postage costs :)
