[LAU] Which keyboard to buy?

Hi all, I am planning to by a second keyboard (once I really talked my wife into it:). The primary reason to do so is that a keyboard with faders and knobs costs less than for example the M-AUDIO UC33E (http://www.thomann.de/de/evolution_uc33e_usbcontroller.htm). So I am thinking about a keyboard in the 49-keys range, either the M-AUDIO OXYGEN 49 (http://www.thomann.de/de/maudio_oxygen_49.htm) or the EVOLUTION MK449 C (http://www.thomann.de/de/prod_zoom_AR_166415.html). Has anyone recommendations in regard to stability, usability and linux-/standards-compliance? (I remember a time when m-audio-devices seemed to need a firmware?)
