Hey, I'm one of the two speakers :)

The commenter above you phrased it well: "Price-reasonable", to us, it's first about breaking even.

I will look into the companies you linked, looks interesting!

Though to give you food for though, I will tell you about a french drone manufacturing company, they manufacture in house, they turn over probably around 10 million € a year.

I know first hand they stencil print around 10k boards a year using a "machine" that is 2x4's from the hardware store, and a credit card :)
