Yeah, I have all of those other than Oracle (it tends to be on the poorly reviewed side).
That said, I've used Nebula and Glitch before. Glitch I used on a guitar part that helped "make" one of my tracks. Unusual use. Haven't really used Kara yet and don't think I put Ravage light on any project so far.
I ended up grabbing Axis (their muti-band comp). Not that I really needed it since Cakewalk's MB-Comp is excellent. But the stereo imaging at different bands, and "L-R" balance at different bands might be fun to play with.
Thought about the Scaler 2 tutorial videos, but at $18 seemed a little steep even though it is on sale. I'm hoping that David from Scaler continues to put out videos on it that might make that tutorial package redundant.
