This one is a wide nut model ( 1 3/16”) which gives you just a little more room to work between the strings.  This helps with accuracy for folks who also play guitar, it’s less of an adjustment to go from a guitar to this neck.

For folks looking to spend as little as possible, but still get into a good quality 5-string resonator bluegrass banjo, I usually recommend starting here.  It's rolled brass hoop makes for a good, crisp sound while reducing the weight of the banjo significantly.
