The KORG Prophecy is in mint condition and it works without a single flaw. Some sounds are impressive, but I'm simply the analogue guy. I might like to try the Z1 one day, though. But the Prophecy cooled off my GAS for one. But all those wheels and controllers are very nice and make some sounds very organic and kind of "real".
The X-911 is awesome. It has CV and Trigger In and Out as well as Filter Cutoff and FM jacks that can be used with external devices. The tracking is a lot, lot better than that of the External Signal Processor of the KORG MS-20 Mini (the X-911 manual says that it's basically a KORG MS-03). With the trigger and CV options I can now use the guitar synth to play my MS-20 Mini or Mono/Poly with guitar (or bass or whatever).

The "Instrument" and "Synthe" sections are very similar to those of the KORG Sigma (KP-30). Very basic on first look, but those modes interact with each other. And it has some funky envelope filter modes (glitchy if played polyphonic, due to the triggering via the Synthe section) plus a hidden Slow Gear mode!
