Perhaps I could get a show of hands from those who think they would actually buy a kit or board that would require assembly docs?
Yes, this would be my preferred way to go

. But I'm obviously not buying large volumes since it's gonna be done manually.
Yep, me too.
Have the skills to do it so i'd like to make a 16 chip Klondike and 4 little USB ones with the 20 chips I have coming soon.
Have you got a plan in place for supplying kits to people? (for ordering and logistics) I'd assume there would be a fair bit of demand. Most people would probably go for a pre-made option though.
