Is there a list of bare boards and/ or kits available?

IMO, a bare board tends to be daunting to those without the skill to at least try to debug the situation. I tend to force myself to learn things by jumping into the deep end and taking my lumps in the school of hard knocks. If someone is building through hole systems and using things like sockets, the odds of borking a board go down a lot. Especially if the design is amenable to sectional testing(like the Arduino Pinball Controller).
EDIT: I mean this as a positive, btw. It tends to self select the people last likely to need hand holding. Not to mention that a large part of these boards are for testing, which further self selects for people interested in circuit repair in the first place.

I know of someone working with the original Williams supplier. They can get every color, in the correct gauges. But, the catch is that they have to buy by the spool, and it can add up in cost quickly. If enough people were interested, they might be willing to sell wire by the foot or something.

That white display looks so damn good! If I had a black and white BSD conversion, that would be the display to use.
