IMO the Korg nanoKONTROL Studio is one of the best of the lower price hardware control surfaces.  I use it daily in my office.  The nanoKONTROL 2 is also very good. For motorized faders,  Mackie MCU, Presonus FaderPort 8 or 16 and Behringer X-Touch are all good.  The Icon  series are good too, but you need to be careful to select a model that actually supports Cakewalk/SONAR.
