The Prusa MK3S Kit was purchased in 2019 and built in about a week. It is a very professional quality kit and relatively easy to build. The resulting printer is extremely high quality compared to most of the low cost commodity printers on the market. It has turned into my workhorse printer that just prints, no issues, tweaking, or fiddling required.
This is also the printer that was used to print all of the parts for both the OpenAstroTracker and OpenAstroMount. Total print time for the OAT was over 24 hours and the OAM was several hundred hours of print time.
