There are some Voron builds out there that are pretty impressive, and can be done cheaper than the $1800 bamboo, but....you have to build it. The Bamboo is, from some youtube reviews, pretty good (and fast), but its cloud based proprietary software etc is offputing to me. For some it wouldn't matter, though.
I want to build a Voron someday with multi filament support, and a 350cubed build volume.
