All of the online dealers I've checked are out of stock on the whole gearset (even Hobby People, who are the US distributor for Sanwa), but most places have the C gear, it's about 3 bucks. Shipping to me is about $3, and shipping from me to you (USPS First Class International) would also be about $3-- so about $10 USD for a single gear. I can also check at the local Hobby People next time I'm there to see if they have the gears/sets in stock, save a bit on shipping.
