Wow John, that is fantastic, thanks for taking the time out of your schedule to whip that up. 
I especially appreciate that this is a leap of faith for you inasmuch as it competes with your kit already being sold by Hennings. But it is a great help for those of us who want to roll our own, and don't have the talent or time to whip up our own board design, and find thru-hole building easier.
It should be possible to make a 100 ma version simply by switching R1 & R2 to 12 and 50 ohm values respectively, correct? I may also poke around and see if Digi-Key has a larger value C1 cap, still in a 10 mm body style and 35V, accepting that it will be taller of course.
As always, my hat is off to you! 
Rod
