The CPP offers digital temp control over the CPA2. FOr up to 5 rolls a day, a CPE2 will do the job for even less money. The big advantage, IMO, is that if you swithc what you are doing, the CPP is easier to set the temperture versus the CPA and CPE. You just set the digital temp and give it time to equilabrate.(posted 8526 days ago)Whatever model, budget a Lift. It makes a BIG difference in using the processor.
For B&W the warm up time will be minimal unless you keep your darkroom very cold.
But for a 5-6 roll every day, I would look at the ATL series. You load the drum, put the chemistry in the bottles, push a button and walk away. When it is done, you hang the film to dry.
