All of the NI stuff is pretty special.
If you go and buy a copy of 'Computer Music' magazine then on the cover disk it has a couple of nice free versions of
Rob Papen Blue
BLUE synth: FM Synthesis, Phase Distortion Synthesis, Wave Shaping Synthesis & Subtractive Synthesis
and u-he Zebra
u-he.com - Zebra
As far as I know these are not cut down versions of the original (non CM) versions
The Zebra is really very very good
