I haven't made any headway yet. Two reasons, first I've been traveling pretty extensively, the second reason is more relevant.
When I spoke with Rogan, they told me that someone else, someone who I would absolutely defer to should he decide to move forward, was inquiring about having a run of the same knobs made. I'm thinking that with their 500 unit minimum, 1000 of them would be a serious glut of them in a somewhat limited market.
I haven't heard back from this other party as of yet, however I will send the "George" knob, sitting in front of me as I type this, to Rogan next week and at least get the firm quote and report back.
