Doepfer

hello,
I'm thinking about getting the vocoder modules. 

A full vocoder is six modules, 
A-129/1 + A-129/2 and 3 of A-129/3 slew limiters with A-129/4 slew 
controller and A-129/5 voiced/unvoiced detector.

But, it is quite expensive and takes up more than half of a G6...

So, does any other configurations make sense?
Can I use the vocoder without the slew limiters?
Without the voiced/unvoiced?

Does anyone on the list use the vocoder without all six modules?
Can you make anything useful out of just the A-129/1 analysis and A-
129/2 synthesis section?

My experience with analog vocoders are the Roland SVC-350 and the 
Korg VC-10. (besides som virtual analog and software that i usually 
find boring).

How would you compare the Doepfer vocoder system to the SVC-350?

Thankful for any buying tips from a-129 users!
