I’m right there with you, having just priced out my first machines. I found one for the ShapeokoXL here:
This item is unavailable - Etsy
I don’t know how much they pay for materials but I can do one for the XXL in aluminum for $319 or HDPE for $78 and I have access to a Haas with rigid tapping so the holes should be quick and easy.
Now I just need an X-Mist. I’ll be seeing you soon!
