Bud,
Not to worry about Humbrol availability; one of the three LHS's I visit in the Big City actually has a really good stock/display. The Postal and cross border service folks have definitely put the "fear of God" into the retailers here; no one will ship anything even remotely close to paints, thinners, etc. etc. Probably a good thing in the big picture but certainly annoying to the fellow trying to indulge in his hobby three hours + away from a source of even the basic paints!
Cheers,
Lance
