I picked up an Ender 3 S1 Pro a month ago for what would be about 350 Euros. I hear about all the problems people have with Enders (now that I bought it) but so far it’s been a good unit. Been using it most days since I put it together, with no real issues with the unit itself. Any problems I have dealt with are just me learning to use it properly or figuring out settings for the slicer software. The Pro comes with all the upgrades already installed that people with earlier versions seem to be trying to add onto theirs. It lacks WiFi, but I started running Octoprint off an old cell phone about 2 weeks in. Can upload gcode files, start prints, and monitor the system using the phone’s camera from my pc upstairs. In time I may start running into issues, but for now I’m happy with this printer.
