Hi Terry, and a warm welcome from the east of England.

As to the cost of film, Kodak and Ilford do their popular films in bulk rolls, that you spool up yourself at home. I don't know the costs nowadays, as it has been a while since I used 35mm, but it will probably come in a t a couple of dollars per 36 exp spool. When I used to do it, I didn't have a bulk loader, I just loaded it in the darkroom, or in a dark bag.
