THought id post this here as its more relevant,
I have a Few Famicom disk system replacement belts, ive sold a few to a couple of guys on the boards and so far they all seem happy because the exchange rate has changed alot ive had to up the proce to $10 incl shipping for a belt. Saw one of these sell on ebay for $20! so i think $10 is pretty fair.
can also offer help on how to fix drives if you have problems..
