Cheers guys, yes I do want another project, but not yet.
I've sworn by all that is holy to me that I'll finish some of the half dozen major projects around the house that I've started but not finished. I think if there's less building material lying around the place I'd have less problem bringing home another bike.
So now I suppose I've got a few months to think about what bike I'd really like to do next, which is fun to do anyway. So far I'm thinking '76 YZ125, '77 CR250, '84 KX125, or something pre65? We'll see how the list looks by Christmas.
