it should definately be on the list
I still own a kurzweil pc3x(mostly because i am still unable to sell it) and the vast architecture is incredible... the most advanced synth available in hardware, but also very. Hard to program... but there is a huge community freely sharing what they created
However compared to the Montage it falls short where it comes to key action, aftertouch, aprs (are much more advanced on the montage), it has no knobs, and the interface is much harder to use quickly...
