revdocjim,

Did you find the GS645 any less reliable or sturdy than the GF670? Is the main reason for sticking with the GF670 for the larger negative or did that camera feel more assuring in your hands or better ergonomically? I'm thinking one of these two but probably the GS645 since it is cheaper and maybe "upgrading" in the future if I'm OK with the folder limitation and ergonomics.
