So I shortlisted my choices to your recommendations, I think i like to have 1 that is already built, so it's the voxel or adventurer
I have noticed that the adventurer is much cheaper, but the resolution is lower, I don't know if that is a major concern,
I have heard about the filament issue with having bigger ones but can be resolved by having a spool holder.

I have a few more questions if anyone knows.
Can these use any 3rd party filaments?
Can they print from petg and wood filaments?
The inventor ii is only ?20 more than the adventurer, is that any good?
Are any of the cheaper monoprice models any good?

Also why are they so big? I need to see if I have enough space to put one
