I'm definitely an advocate of Happy Nerding's stuff...their 6 hp mixing/VCA modules are an awesome way to drop more functionality into small builds without spending loads of $$$. As for the PanMix...don't JUST look at it as a mixer. Rather, view it as a pile of dedicated VCAs specifically for your audio chain...which is pretty much what it is. By relying on the mixer's VCAs for the tail end of the audio instead of some VCA-specific module, you can then make more use of your VCAs for CV/mod purposes, which just makes that set of subpatches that much more powerful. Although, I do like the Stereomix 2's implementation better, as that gives you simultaneous level/pan per strip, PLUS you get the AUX bus setup on top of that...and that last detail, with its own VCAs, has loads of "abuse potential". Coupled with a reverb, for example, you can use simultaneous CV changes that allow the reverb to act as a stereophonic "Z axis", with the ability to emulate forward/backward movement into the stereo field.
