I love the ProControl, everything is nicely spread out and not cramped. The HUI is a peice of shight, faders flying out of control and locking when trying to write...GRRRRR!, don't bother. If you're purchasing a used procontrol there are some things you should consider, The analogue section has been upgraded in later units which fixed the polarity problem with the main output, noisy buttons and the headphone amp was replaced with a louder one. On older models the rotary encoders in the DSP section were a click/stop version which are really annoying, not a big deal to get changed by a decent tech. Arm rests are another issue, older models had a crappy rubberised paint that comes off so a replacement arm rest might be in order as well. Faders are cheap to replace, about $150 yanky dollars if I remember correctly. Good Luck! Stefan Nowak
