I bought the bare double board and ordered the parts from Mouser, mostly from the parts list on this site. I made a few different choices for some connectors to suit my needs, otherwise; built as designed.

Some tech notes for prospective builders:
1. Quality of bare board is excellent! Solder pads are crisp and clean, easy soldering.
2. Solder mask and artwork - top shelf. Component locations clearly marked; I still strongly recommend printing out the assembly guide.
3. It works well! Good design, op-amps are socketed for a good reason. Let the blue smoke out of a few just for fun, positive feedback rocks! Bought spare op-amps from Mouser 'cause I knew I'd need 'em.
4. If you are not really comfortable with hand soldering, get the assembled unit; this is not a project for novices.
5. Go nuts! I'm tinkering analog and digital screams.
More later.
