Not to be disagreeable, but I have a number of badger brushes I think of as quite good, brushes which cost less than $50. I'm not sure anyone would call these great brushes, but great is subjective. These are certainly good badgers.

No offense taken. I know that good badger brushes can be had for under $50, but many of the badger brushes in this category are either lower grades of badger hair (pure badger or best badger), small diameter knots (under 24mm), or low density knots that provide little backbone. So you need to do a little research to make sure you will be pleased with the results. I do agree with you that two-band badger brushes are likely to be your best option in that price category.
