There are different Polaroid backs. I assume for different films, or are
they just "upgrades" and all take the same film? I know that Polaroid has
stopped production of some of their stuff. Do I need to worry about
back/film compatability?

Any thoughts or experiences on the RB mechanical vs the RZ electronic
shutter? A concern is getting a used camera that is being sold because it
is waaaaay past its shutter life and needs to be rebuilt.

Pretty much all of them take 600-series 3-1/4 x 4-1/4" pack film,
unless they specifically state 4x5 or otherwise. There are some
subtle differences between backs - just look for ones that don't
require a special P-adapter for the RB. The NPC MF-3 is perfectly
servicable.

A CLA and shutter timing from KEH on Mamiya "C" lenses is around $140
on average. Typically, it's the slowest speeds that first start
showing timing problems with the Seiko shutters. If the shutter needs
replacing, I'm sure it'd be considerably more, but unless it's a real
beater that's usually not required.
