(SORRY Steward, only just read the post about not wanting to make a commercial version, however saying that some of us cannot solder for toffee and have a huge interest in super small handheld so I hope you change your mind one day, however if you I fully respect that)
I for one will be 100% interested in buying one these... Let em know if you ever decide to release them for sale, I will certainly buy one for me and one for my son if you do
It would be a great Kickstarter project, or even a great privately funded project... Whatever you decide I will back you or respect you choice if you never sell them
great work !!
