I have the 350s, and they're great. I bought them at Honig's last year around this time, and they have a nice "black" option. Okay, it's not 100% black (there's some minor trim that's silver, but that's easily Sharpied). However, the big "N" is black, not silver.
Unfortunately, since they're discontinued, Honig's doesn't have many of the regulars left. They do, however, have a bunch of the wides.
As far as I know, they're the only vendor that carry them with this black option.
My only complaint is the way the panels on the front-inside meet up. You know how Bubba The Catcher likes to take that step back in SP games? Well, if he catches it just right, it will loosen the stitching between the leather panels.
