Will Wright’s take

Based on the specs and price

Solid choice

“The tinkerer's workhorse: open, repairable and built to last.”

Prusa doesn't chase speed numbers, but you get excellent first layers, a kit option and parts you can actually fix yourself. It's pricey for an open bed slinger. You're paying for openness and support, which is worth it to some people and not to others.
