I *loved* the CZ101, it was one of my first synths and I held onto it for years, expecting the (obvious) plugin version to come. For it's time, it was an incredibly important, and popular/affordable - and great sounding - synth.
The plugin never came, but I eventually somewhat reluctantly sold it for pennies as I needed to downsize.
I missed it, and eventually picked up a CZ-1, which is *by far* the best CZ of the range, and *way* nicer than the CZ-101, with perhaps the intention of doing an emulation (because no-one else seemed to be doing one).
(That the CZ-101 can command higher prices than the CZ-1 is absolutely crazy to me.)
A year or so later, Oli's VirtualCZ came out, and I regrettably offloaded the CZ-1 again (for less money than CZ-101's are going for), as what I really wanted was the sounds etc in my DAW, not a room full of hardware.
I'm still extremely fond of the CZ's to this day.
VirtualCZ is a *steal* at these bargain prices - it cost me 6 times what it's selling for now, so at least 6 of you should go pick up to balance that out...
