I've never owned a real "luxury" brush, but I've owned a few Simpson's Duke brushes - what I would call entry level luxury. As in most luxury items, luxury brushes are not the best bang for the buck. Which led me to thinking about what brush does provide the best bang for the buck. From my experience, it's not going to be a badger brush. You can get a very good synthetic or boar brush for under $20, and I haven't found that to be true with badger brushes. I've owned 6 brushes that fall into this under $20 category, and my candidate for best brush under $20 is my Zenith B70-Euroal at $15.50 delivered. Any other candidates?
