Original Prusa MK4S
Open, repairable, and built to stay on the bench for years
$899
The MK4S is for people who want ownership: open-source DNA, excellent documentation, and a parts ecosystem that assumes you will keep the machine a decade. It is not the cheapest path to speed, but it is the most reassuring.
