I have the Jobo slot processor, and single wavelength safelights, plus a couple of Beseler Minolta color heads for the 45M.
Jorge in Uruapan broke me in, though with what I consider more difficult negative filtering. The Beseler Minolta heads are additive, so if I need more cyan, I add more cyan. Settings are adjustable to around .01cc.
I found most films printed with a very similar setting, and wrote them down for starting points. The printer will retain the settings for quite a while even turned off. The chemistry I mixed myself at first from the Kodak kits, the paper was cheaper than B&W in recent years, the actual processing took a couple of minutes with a quick wash and hang up dry.
I have a friend at a photo shop with a mini lab, and as he mixed in bulk, I began to get my chemistry pre mixed from him, the stuff keeps very long in the processor, with continual replenishment by adding stock solution as the levels drop.
RA4 is just about bullet proof, and I quickly got results much better than what I was getting from commercial labs, printing formats they turned down (6x9cm), and able to dodge and burn.
The processor was not cheap, but really not too expensive, and takes a very small footprint, printing up to about 12x15 inches, Jobo supplies a clip for the paper, with 45 seconds in developer, 5 seconds in stop, 45 seconds in Blix, a rinse (processor has an extra slot in case you want to use Ilfochrome) then in to the sink for the normal RC wash.
Finally, someone basically gave me a roller processor at a camera show, which will handle up to 8x10-- Luck may play a role. ;-)
Last price I saw for the 45M color head for the Beseler was about $150, including spare tubes.
