Doepfer

You are indeed an intense vocoding wildman.  I should point out that
someone newly experimenting with vocoding could get 80% of the way there
with the analysis and synthesis modules and a preamp and something
feeding the instrument input -- richest choice obviously being sawtooth
waves.  All right, perhaps also the voiced/unvoiced detector. 
Everything else builds from that.  I also believe that for simple
vocoding, there are cheaper routes -- the real beauty of Doepfer's
version is its complete open-endedness.  Frankly, it can actually sound
a little dirty, not that that's necessarily a bad thing.

And now, senseless rambling about cases and aesthetics:  I *love* the
idea of a 4-row 168-hp case.  I've got 9 84-hp rows in a couple of
Raxxess racks, which is fine but inelegant.  Then again, when you start
patching up those closely-space Doepfer modules with skinny
technicolored patchcords the look becomes inelegant pretty fast anyway. 
The Doepfer is a kickass modular cleverly disguised as cheap lab
equipment.  I really just care about the sound.  I like the looks of
Analogue Systems' case, but it's so expensive.  Somehow Synthesizers.com
manages to offer a great-looking slanted case for much, much less.  I
wish it fit Doepfer-size modules.  

If Synthesizers.com offered anywhere near the module catalog of Doepfer,
I'd be severely tempted, both for ergonomics -- big knobs, large
real-estate -- and jacks longevity.  I need to find some impoverished
person surviving on beads of solder to do a massive banana-jack
retrofit.  That would render the machine immortal.  I'd never trust
myself to do it.
