Very generous offer! I'd be more interested in your opinion of my general 
module proposal. Maybe instead I could offer to drill a panel for you, and 
you could build a similar module. I'm also thinking how much such a diy 
module would cost to build:
(from memory)
1) MOTM breadboard = $40
2) MOTM 2U FP = $22 (?)
3) pots = $40 (7 X $5.50 ?)
4) knobs = $13 (7 X $1.70)
5) pushbutton & LED = $8.00
6) jacks = $14 (7 X $2)
7) resistors and capacitors (nothing special) = $15 (guess)
8) semiconductors (a couple of TL074s, maybe some trannies) = $5 (guess)
9) CEM 3310 = $42

Anything else?

I guess about $200 -- not too cheap, but a very useful module. I'll think 
about this, and maybe try and build something in a month or two. I guess I 
need to figure out how to limit the voltages (from the inputs + the initial 
setting knobs) to 5V per stage.

Still thinking!
