I have an excellent scanner, Canon 9950f (now discontinued), which I've used for several years scanning hundreds of old negatives of various sizes. Trouble is, the plastic film adapters (or frames, or guides) are shot. I'm looking to buy a new (or relatively unused) set. If I had to, and the price is right, and it's in good condition, I might buy another 9950f just to get the adapters. Anyone?
