Sir Space, FWIW, IMHO, just look around for a nice pure or best badger brush.
Does not have to be two- or three-band.
And you can find them for well under 80$!
Main issue in your case, might be shipping costs.
Enjoy your journey!!
I'm sure some nice Best Badger brushes can be found, but I haven't found them. In your price range would recommend and Envy Shave or Elite Razor brush with a custom handle. There are plenty of makers where you can find a handle to your liking. I personally would step up to a Declaration Grooming knot, but that might stretch your budget. Or I'd recommend stretching the budget to $150 and watching the B/S/T for some Paladin, Simpson's Manchurian or 2 Band Silvertip, Shavemac, Declaration, Morris & Forndran, or Brad Sears.
