I was searching for answers to the same question in this topic recently, and came up empty. It would be nice, but I assume that there is not enough demand for this item.
I have a stinking mini keyboard that I would like to use with my mobile laptop, and not have to drag a larger controller around. But it lacks pitch bend or mod wheels. Just great! These controls are absolute must haves for synth patches that are programmed to use them. It came with a bundle, so no big loss, but I would recommend buying a complete controller with everything that you will need.
This Nektar Impact LX25+ seems to be the most complete compact keyboard around. Even has 25 full size keys, plus pitch and mod wheels! At less than 19" wide and 11" deep, the footprint is not too bad. Selling for $99 at various online retailers.
