Get the hardware! The elysia video floating on gs looks sick.
Elysia Alpha. Bar-none. Well, for 2-BUSS duties anyhow. Amazing feature set and great sound...... the soft limit is great and the warmth can be cool if used sparingly
To my knowledge Fabfilter make one, I've read nothing but good stuff about it

Brainworx have an entire pallete of mid/side processing tools (actually, I think that all their plugins have m/s processing), but not the compressor, just a mastering limiter.
In the studio we have this (not mine, sadly)
i grabbed the 14 day demo and im VERY impressed!!! thanks man
