In the past I used both a Beseler unit (it reversed) and two Unicolor units (one didnt reverse). The beseler motorbase was much faster than the Unicolor ones, so times were very short. Not sure if this was just my unit, or if all Beselers were like that. Try to find some Unicolor 8x10 Drums. You can do 1-4 sheets of film in them. The LF site has an article about it.
