JandC is probably your best bet, unless you see some on a shelf somewhere, Tom. At least you know it's fresh from JandC, and you won't get some guy trying to charge you $10 for shipping with the ebay route. JandC shipping is quite reasonable. I just ordered 30 rolls of film from them last night, and Priority mail for it was $8.
I live in a small town (3500), and the one hour photo place here can still do 126 on their machine, which is a fairly modern unit. Robert, the store owner told me it runs on the same track as 35mm film. I had a roll of old Kodak 126 done there about a year ago, and walking out of the store with 12 4x4 in prints sent me back to 1968, a kid again, with fresh prints from my Instamatic.
I think Wal Marts still do 110. Don't know about putting stuff on CD, though.
