I found a Frankona stoneware mug at an antique store for $10. I think it might have been intended to be a soup bowl? It's wide enough that I don't bang the sides with the brush handle, and I can get my hand in there easily if I'm using a stubby brush. I love it. My lathering got a lot more consistent immediately when I started using it. Only downside is that a brush without a lip on the butt of the handle will slide into the bowl.
