Just to add an extra data point I was able to get my ender 3 pro for $100 when it was on sale at microcenter. My experience is it works great for awhile and then I have to spend time watching videos and reading comments on how to fix random issues my ender 3 pro has. It has not been the most user friendly but hey, it was a cheap printer. I also have upgraded mine with new silicone spacers or whatever to keep the bed more level in between prints as well as a new hot end, oh yeah also the filament tube. I still love it though!

Just a heads up that Nova might not be the best from for your privacy if you care about that: https://www.makeuseof.com/nova-launcher-branch-is-it-still-safe-to-use/

I used to use it as well but have moved on.

What configuration yaml changes? Now I’m worried.
