Sorry I didn't fully read... Well you can always spool it onto 116/616 spools and shoot old folders and box cameras that are 116/616 in size (like me).
Also you can get cheaper 70mm backs... I'll sell my hassleblad 70mm back for $150. I think I got my 70mm mamiya for $300, you kist have to be diligent in searching.
