Hi all,
I like to suggest to have a look at :
http://www.techrepairs.freeserve.co.uk/The quality of the midiDAC is very good.
I've built two of them - one to control the MOTM-system, the other one
controlling the rest of my modules.
The design is somewhat MOTM-ish, that is a good DAC (12bit), fast
voltage followers and a stable reference voltage source.
You do need to "design" Your own panel, though.
