Perhaps I'm going a bit over the top, but I've just bought an HDCC-150 supply. This is the largest of the generic linear regulated supplies, and is very rarely available. Presumably, it's also the best, so I'm keen to try it out.
Its natural place is in a 861, but I have a feeling it might be too big, due to the capacitor board. I'll probably have a play with it, and then offer it to someone else for a G68, either as-is, or with mountings & connectors, or fully fitted. It was too good an opportunity to pass by.
