I'm relatively new to LF. I was introduced to developing 4x5 negs using the Jobo Expert drum; however, trying to find these on the used market has not been fruitfull and the motor base agitators are even more difficult to find. The Jobo Expert would have been key in addressing a space problem. I don't have the space for trays, or tanks. Even if I were to bite the bullet and buy a new Jobo drum, the motor bases are like really scarce. Is there another alternative to the Jobo drum?
