Shooting photos with 110 film cameras is remarkable for the same reason that tap dancing elephants are remarkable. What's amazing isn't that they do it well but the fact that they do it at all.
I agree. I'd much rather see, in rough order of preference, 1) 620 2) 127 and 3)126. I know you can respool your own 120 onto 620. You can also buy some films respooled but they're too expensive and a bit limited. I have some such respooled TMX loaded into a Kodak "faux TLR" my wife then-girlfriend got me, and I paid just over $10 a roll for it. I just shoot it for a lark though. A baby Rollei is pretty nice and there are tons of Brownies and such that can use 127. The baby Rollei will blow the lens off any 126 camera, which are themselves better than a 110 equivalent.
The cool cameras in 110 were the Minolta and Pentax SLRS. I admit they are kind of cool but the image size...ah, much rather have a Pen F half frame.
