The $300 Elegoo Mars 3 is the latest in the Mars series of printers, and Elegoo has clearly listened to feedback from their users. The 4K screen on the Mars 3 provides razor-sharp detail without compromising on print speed thanks to a brand-new high-output COB UV LED light source that enables rapid 2.5 second per-layer cure times. 

During testing, this printer proved to be accurate and reliable, but falls just short of being one of the best 3D printers due to a poorly designed test print, a cheap-feeling plastic case and the fact that, as of publication time, the printer was unavailable for purchase. If your primary concern is resolution and speed, than the 0.035mm XY resolution of the Elegoo Mars 3 makes this printer absolutely worth the price for fast, high-resolution printing.
