No real downside, partcularly since it's free. A CPP2 will have great utility for someone without access to a full darkroom sink, even if only processing B&W. Terrific for E6, incidentally, so you'll not have any difficulty turning a buck on it should you decide it's not your preferred way to work. Might also mention that if it has one, the Lift can be a most useful accessory but it's quite a bit vulnerable when moving (suggest disassembly of the lift arm from the unit).
