I'm not sure what you have planned for the knobs but these may be useful. I've got a set of the Kilo knobs from digikey that I'm going to experiment with over Christmas. I've also got a couple of the MGW knobs on order. They have several different styles. I'll post some side by side comparison photos for the Kilo knobs.

Note! The set screw in the kilo knobs are approximately 1/4" from the end of the knob. The NewFace is 1/8". To get the Kilo knob to work, I had to remove the lower lip on the knob (~1/8") otherwise the set screw doesn't make contact.
