Mathew,
For films up to 8x10 you need the appropriate drums: a 3005 holds five
8x10's or 5x7's, a 3010 holds ten 4x5's or 5 5x7's.
Then you need one of the larger, but not fully automatic "bathtub with a
motor" Jobo processors. The smaller ones can't hold Expert Drums. One
model has a circuator pump and a simple thermometer and dial for control
of temperature, another has an automatic thermostat. I'd save the money
and stay with the fully manual model. You must have a "Lift" and also a
footpump for removing Expert Drum lids. The machine handles temperature
and agitation. Once the drum is loaded, all you do is time the process
steps and pour solutions in and out via the Lift.
It's only a few items, but it will set you back at least two grand. Very
convenient, but since it is entirely possible to learn to process
excellent negatives in trays for an investment of under a hundred
dollars, you've got to decide how much you're willing to pay for
semi-automation. If you have any interest in doing color film as well as
b&w, that's a strong argument for the Jobo because of the ease with
which it handles near 100F temp processes with small chemical volumes.
The current issue of _PHOTO Techniques Magazine_ has an article which
includes _very_ detailed step by step instructions for processing pyro
negatives in both trays and jobo-style equipment.
