I remember over 25 years ago, I worked in a college photo lab and we had a system that used Jobo drums. It had a nitrogen system to pump chemistry into pots to get heated and the machine would dump the chemistry into the drum at the right time. The drum was housed in a heated cabinet. It was sure slick. We ran mostly E-6 and made Kodak R2000 prints.
As for me, I don't process enough prints or film to justify having one. I just use my thrift store Beseler agitator base and Ebay drums. Ghetto, but it works.
