I'll cast my vote for developing sheet film in a light tight tank. I get to work with the lights on. 12 sheets at a time. The size inside the tank can be varied to do smaller sizes of film. I think the tank only cost about $30 or so at B&H. It spills out the top a little as I agitate, but that can be kept in control by doing it over an empty tray were all the chemicals spill in to. I've been using mine for over 2 years now and couldn't imagine going back to trays.
