Of these options, I'd recommend the SV08, provided you are okay with some mods essentially being required for consistent, reliable use.

These being:

- Eddy sensor (for faster bed meshing, eddy-ng addon for Klipper adds auto z-offset)

- Mainline Klipper/Kalico (required for eddy functionality)

- Some motherboard fan replacement mod (the default is tiny, noisy, and always-on)

Of the others listed:

- Bambu printers and the Elegoo Centauri Carbon have locked-down firmware (possibly with hidden license violations).

- I think the only Prusa machine with that build volume is the XL, which is out of the price range

- The Creality Ender 3 V3 KE is okay, but the build volume is 220x220x240mm
