Okay, Tim, I *know* you must know this, but just for the sake of the archive...
You can still buy three emulsions of new film in 127, all on Efke-made spools: Efke R100, and both C-41 and E-6, ISO 100, from Maco. Be warned, however, the Efke spools reportedly don't work in a few 4x4 TLRs. All three are available through APUG sponsor J&C Photo.
They also have 126 cartridges (ISO 200 color prints only), and 110 cartridges (same film as 126), for whatever that's worth.
