328DTM - well it depends on what you're shooting. I'm usually taking pics of candids and moving targets - so if I'm LUCKY - I'll get 2 or 3 keepable shots out of a roll of 36.
Usually I'm shooting B&Ws so the processing fees are a bit more expensive than your typical 1hour jobbies. Plus it takes about a week or so to get it developed.
Instead, I will be able (once i get the digital) to shoot a ton - delete the crap ones - and only print the good one(s) all in the same hour.
Totally worth it to me.
