Waves has their CODEX wavetable synth on sale for $99. It looked interesting so I got it.
I've been fiddling around with it for the last couple hours and I must say it's pretty cool. It automatically converts waves to wavetables and splits them up so it's really easy to import a just about any sound sample and slice and dice it in interesting ways.
It's definitely a nice bit of kit to have in the toolbox.
