Very nice, Neil! (And here's that same image, but with better visibility of the fine traces.)

intermittent contacts (and the same every time I've used the damn things in the last forty years)
Solderless breadboards do seem to have a bad reputation in this regard. And it's easy to believe a breadboard with intermittent contacts will eventually exhaust one's patience and lead to defenestration of the offending item.
That said, it would probably be a mistake to paint them all with the same brush. IOW, I suspect the quality varies widely from one brand to another. I have limited experience with solderless breadboards, myself. But, acting on Radical Brad's advice, I chose to purchase Twin Industries' breadboards, and -- so far, at least -- my blood pressure and cheerful disposition have suffered no ill effects.
(But they're still no substitute for your protoboard, as they don't accommodate SMT.)
