Cool! I didn’t see the post of yours. Do you have a link?
I am the goto guy for 3D printer problems in my friend group. Contrary to the other printer models, the guys owning Ender 3 only contact me to show me the cool things they printed. These things just work. I only have one friend who has an Ender 3 who had problems with it, and that was after he upgraded almost every important part at once and had trouble getting it all working again.
There certainly are better (and much more expensive) printers out there, but for the price point it’s absolutely the best. I would recommend getting the newest version.
I would recommend buying a new one, if possible, because there are lots of unobvious ways to break a printer and fixing one if you don’t really know a lot about printers yet (because it’s your first one) is really difficult and frustrating.
