There are usually quite a few deals on C3s on fleabay. Look at the photos and you cn tell if they have been cared for or been allowed o knock around in a boat. There is nothing wrong with the old C3s and can be had for half the price of a new one.
I currently have 6 of them that came from fleabay. It's hard to pass up a $50 deal on one that looks brand new regardless of age.
