If I listen to Phillip Hodgetts's opinion on using Color, I would need to spend $20K setting up a room for it... And, in actuality, I have a room that is not too far off from what he describes. However, one of the sticking points is a control surface. JL Cooper makes the cheapest one that I can find at $5K+.
Looking at their unit, I see:
3 backlit trackballs.
8 toggle buttons with indicator LEDs marked Page 1 - Page 8.
6 pots each adjusting a value indicated in a digital display.
6 more buttons with LEDs.
And a case that looks like it was built to withstand a war. Clearly, from the looks of the thing, they have used top notch components and I know it has some I/O expandability.
Now, for all of the new Color owners out there, this seems to me to be a golden opportunity to make a scaled back type of unit - Something on the order of < $1K.
So all of you entrepreneur types, get on the stick here. I want one!
