Greetings,(posted 8366 days ago)People have different preferences, but I like the JOBO rotary processor for developing film. It's fast, consistent and very efficient. If drying time for drums and reels is important a hair dryer works very well in shortening that time to nothing. The problems I see with deep tanks, are the space they occupy and the massive amount of chemistry they require. If you're only doing B&W, using fairly inexpensive chemistry, that's not a problem, but doing E- 6 and C-41 can break the bank if you're not doing this commercially.
Perhaps you can find a local lab, school , or rental darkroom that has a rotary processor and give it a try before you buy. Good luck!
Regards,
