I just learned today that Standard changers has come out with a conversion kit to replace the guts of the Rowe BC1400 changer with a Mars validator and 2 Standard MC Hoppers, all your basically using is the Rowe cabinet. Standard has also come out with a new model MC400RL-Slim bill changer. It’s a direct replacement for the Rowe BC1400 bill changer. Same size cabinet as the Rowe BC1400. Since parts for the Rowe changers have been such a problem to get this might be a good option.
