Finally got my KTB after a bad mix up by the courier that led it to being missing in the mail system for some 40 days.
I had made a custom CNC case for it while waiting for it to arrive. Also added an LED for aesthetics as well as a power check due to the enclosed case.
I highly doubt I can bring it down to a price point that will be met with enthusiasm on these forums though. There really is not a lot to be cut in fabrication costs unless it can got into a 3-figure production run.
I did ask my fabricator how much it would cost for say a 20 set run. Including my time and excluding transfer payment and shipping, it would cost about US$68/-.
Looking at how price sensitive the people on these forums are, I highly doubt there will be more than a handful of takers.
