" Glowforge- I’m a Silicon Valley fan and like innovation and continuous improvement approach"
As far I know Glowforge haven't innovated or invented anything. They just repacked old Chinese, outdated (cheap) technology in new plastic (unsafe) body, have terrible cooling and ran dishonest, deceiving marketing campaign in an attempt to pray on the uninformed crowds.
Noone who values innovation and continuous improvement should support this type of businesses.
From your list, Speedy 100 is your best choice in my opinion but of course, there are many other options. It is expensive equipment and it appears you need more information. I would suggest researching more before ordering.
