I use mine for black and white as well. Love it. Perfect consistent negatives every time.
I originally got it because I got into 4x5 and didn't really like any of the other options. But I soon started developing all my 35mm and 120 film with it as well.
The price is a steal. You could buy it and flip it here and double your money, most likely triple if it's in such good shape and has accessories, maybe more than that if it has the Lift.
I do like the lift a lot, though the arm is flimsy so I always just use it to start raising the tank and then lift the frame under the tank with the other hand.
