you missed one of the most under-rated of their releases...the PC1SE 
Added PC1X, PC1SE, PC161
I think they were released in 2005, but I'm not sure. I entered in the company in 2006!

Sounds about right - I had one for a while with the Classic Keys expansion -at the time it killed anything else and with 76 FULLY weighted keys it was a pleasure to play.
I had to move it on only because of the limited editing and MIDI Rompler capabilites. Still it was a 'board I fondly remember
It would be great to see this list on the Wikipedia.org page for Kurzweil Music Systems. It's quite a good timeline.
