have no experience with colour printing. With B&W printing I find the NOVA three-slot processor (no heating) not only a space-saver but also a substantial chemical-saver. I prepare new chemicals sort of every two-three-four months (Ilford Multigrade and Ilford Rapid Fixer) and in between I replenish as necessary. Replenisment is easy thanks to the taps sitting halfway up on the side. I print quite a lot and find I get always consistent results. I also have a NOVA print vertical washer, also 12x16, standing close together they take up only a small foot print.
So = highly recommended!
