In my 13 brush collection my 2 favorites are my Simpson Duke 3 in best and chubby 1 in 2 band super. I'm looking to get a few more simpsons to add to my collection. I'm looking for something with a slightly larger knot (24mm +) and under $200. I'm looking at a chubby 2 in best, polo 8(2 band or best), persian jar 3 in best, tulip 3 in 2 band, and the commodore x3b. Which out of those do you recommend? also where can i find good condition somerset era simpsons brush? especially the duke 3 and chubby2.
