Looking for feedback: MIDI Controller keyboards

Hmmm… that’s what i actually expected.
I thought about using the Numa Compact 2X, maybe in combination with the little Behringer controller-board… but without Pitchbend- and Modwheel: No way.
If there only was a separate wheel-box on the market, but there obviously isn’t such a device.
I really thought about building something like this by myself… there are ready-to-use controller boards from Doepfer and some other makers and i just saw that there are wheel-sets available from Fatar.
I guess, this actually could be makeable… depends on the price and quantity Fatar sells the wheel-set (i won’t buy 100 sets).
