An ATL 1000/1500 works very well. Automatic processing of E6/C41/B&W for up to 5 rolls of 35mm or 6 rolls of 120 or 12 sheets of 4x5. I'm not sure about the long term reliability of acquiring parts as Jobo no longer makes processing machines. Once in a while an ATL 1000 or 1500 shows up on Ebay. Expect to pay between $1000-$1500.
