In my experience, setting up consists using the original Zephyr's built-in throttle was aggravating (I haven't used a newer one with the upgraded screen), but on the DT throttles it's very simple.
DCC systems are like deodorants: "Six took stick, six took spray!" Except we have mores choices, like roll-ons, and wipes, and... Hopefully some of you remember that TV commercial... Otherwise, this isn't very funny.
