Not as in-depth as I wanted it to be, but I'll be doing more follow-up videos on my machines very soon. (Plus people always complain that I talk too much so I guess shorter might be better.)
All of my machines and parts came from Button Boy Inc.-1.25" Machine: https://goo.gl/o9V81B
-1" Machine: https://goo.gl/B97bW5
They have an Etsy shop too, but their main website has lower prices.
