This really wasn't the question, but some may be interested that I use a Jobo drum for processing my 5x7 and 4x5 sheet film. I had heard such terrible things about the motor in the Jobo base, that I built my own rotary base. It is about the size of the unicolor rig, but I put a bigger motor in it. I bought some nylon gears, a toothed belt, some wheels, shafts, and I had some pvc sheet plastic. From this I made the base. I got the rotation speed I wanted (actually I have two speeds by changing the belt over). It is small and the motor will never burn out or stall (unlike some Jobos). Works great. The motor was the big expense at about $100. One could probably salvage a motor for cheap from some other application.
