Note I have a VERY small shower room (and NO bathroom) I have quite space contraints.

I am very unfamiliar with developing film and even more with what a processor could offer.
What exactly does a processor do? What does it allow you not to do?
Is it much faster and/or safer? More (or less) economical?
Since Jobo is in the subject line, and they are very affordable, I will stick to them in this post.
Jobo processors use a stack of normal (although still dedicated to the system) film reels that is put into a plastic tube.
The tube sits horizontal on the machine, and is partially submersed in a water bath.
The water bath provides tempering to keep things at the right temperature, which is critical for colour, and very important for B&W.
The tube is filled somewhat less than half full with chemistry and the machine is started.
The tube is rotated back and forth, providing agitiation to the film.
The processor allows for consistent results in time and temperature critical processes.
It is not faster, as time is a consistent no matter what developing method used.
It can be more economical, as in a Jobo, much less chemistry is used. I can process 10 rolls of 120 film in somewhat less than a liter of chemisty with the Jobo.
The downside of the Jobo type machine is that it cannot be used for certain black and white development schemes, such compensating development, where the film recieves minimal agitiation, and because of the low chemistry volumes, developers with high capacity must be used.
