(I have several Bambu Lab machines, including the P1S)

Prusa machines are quality, and open source, but very pricey compared to Bambu Lab.

I recently got a Creality K2 Plus, which approaches Bambu quality, but it's still not 100% there. So far I'd give it an 8/10 though.

Check out the new Creality stuff and I have a few Elegoo Neptune's that are pretty nice

Not sure, it caught me by surprise as well
