Hey there Godfrey, I recently found this thread about APS and saw your post.
I shoot film since the '90s, but never shot APS up until a year ago when I bought a Canon EOS IX, which I absolutely love, but I'm in very short supplies of film - have about 6 rolls in the fridge.
Do you still have some?
I know it's more than a year since you posted that but maybe you still have some APS.
Thanks
