Even better than the Quad, if you can get it, is the Chrome version which has running water rinse in slot 2. It's superseded, but there might be one floating around in the shops or second hand. I second the recommendation for the 2 slots of fixer. It speeds up the work flow as well as fixing better. Be generous with fixer! With developer lasting for weeks in Slot 1, it requires discipline to remember that fixer needs to be replenished far more frequently.
