I've got a few expensive brushes that are very nice, however, my go-to favorite brush by a long shot is the one I got from whipped dog. I got the biggest silvertip that he offers in a custom ceramic handle. I think it cost about $40 shipped a little over a year ago. His prices have gone up a bit since then, but I think you could get something similar for about $50-60 now. Best money I've spent on a brush... love that thing.

Just an option to consider, and a great bang for your buck!
