Atomstack S20/A20/X20, Too buy or not to buy?

I currently have a atomstack a5 pro+, wanting something with a bit more power to cut in fewer passes and to cut thicker material. Curious if anyone has any experience with these atomstack 20w lasers. (S20/A20/X20). Pro’s/Con’s? Worth the money? Are there better options for around the same price? $1000-1200.
Thanks, Zach

I upgraded from the a5 Pro to the S20 and The S20 has handled everything I’ve thrown at it. Took some trial and error figuring out settings with LightBurn, but all in all the S20 is a solid machine and has not let me down. The air assist is great too.

Good to know, thanks! If I end up getting one I may end up asking you about your setting if thats aright with you.

Not a problem, Thank goodness for pen and paper though. Always need a cheat sheet. I use the Atzer 20 W settings lib. seems to work ok until I can finalize my own.
