If as you say KN7 so many KN7000 owners have or are moving on to other newer instruments...and in doing so have no doubt sold their KN7000s...where are all the new owners of these 'defunct' KN7000s; I'm sure they weren't / aren't all being thrown on the tip and I don't hear of Retailers being stuck with loads of them.
KN7000s don't die, they just fade away from Synthzone...
