Love my Ender 3. Upgrades include a silent motherboard, auto bed leveler, new springs and a glass print bed. This thing is solid. I haven’t had a print fail me since right after I got it. It is set it and forget it for me. I can start a print and walk away. Just change nozzles when needed and keep up on bed maintenance and cleaning. You don’t need to spend $600 on a printer, especially if it’s your first one. Agree with those saying print with PLA first. Make some reef organization stuff, Hanna tester organizers, etc. Then you can take on PETG.
