I have been really pleased with my Edwin Jagger Best Badger brush in the urn style. It was a little "scritchy" for the first couple of weeks, but has broken in quite well. It is miles above what you have been using! You are not going to believe the lathering ability of badger once you try one.
I got the large size (23 mm knot) priced at $59.95. The medium size (21 mm knot) is out of stock, according to the web site.

My name is David, but you can call me Jim, if you prefer. My mileage does vary, however.
