There was a '?' after my name on the list. If that was to confirm my interest in being/staying on the 2nd list, it is confirmed. If it was to confirm Bob is Headshrink, it is also confirmed
Price is very reasonable, no need to justify it. I know we all appreciate all the R&D, labor, etc. that you have been putting into these. If enough of these got out, I would expect the manufacturers of the commercially available units would need to step it up. Might even be worth a patenting your design.
