I've been looking for a numpad with rotary encoders, but something on the higher end with an aluminum case, ~100 USD. Laneware recently had the MACRO-1, which looks great, but $175 for a numpad was brutal. Something more similar to the KBDPAD with an extra rotary encoder or two.
Personally, I don't care much for the OLED screen, but its ok.
Making it QMK compatible seems like a pretty top priority if you are worried about remapping. Hope this goes a little bit further.
