They've thrown some more fuel on my fire. You can put together your own brush. Pick out handle shape, color, knot grade, size, shape. They even have one that's new to me, flat shaped knots. They don't have a link to that service but if you put in "170" in the search area it'll come up.
Yeah, my brother got them to make him some beast of a brush. He PIFed it to my dad (who never uses it)...but it definitely is custom! I'll try to borrow it and post some pics.
You can just purchase knots from them too. I'll probably pick up one more knot from them at some point.
