FYI: Seems there is a new version of these kits for 2017. There are multiple options of ordering just the kit, just the parts, or fully assembled boards.  I might pick up the $16 kit with the plexiglass case just for fun.

On Aliexpress. 

I still plan to try and flash this 2016 kit I have. Then I can do a followup to this episode.
