tl;dr: What is the best quality consumer 3D printer available (NOT bambu labs)?

Hello,

I’m relatively new to 3D printing (<6 months exp) and am in need of advice.

Background: I purchased a used Prusa MK3S+ as my first printer (got a good deal from a neighbor, not a print farm). I had great experiences with it for a few months. However, recently several components keep breaking one after another. I’ve spent ~$100 over the last month replacing parts, and now it seems the power supply and/or mainboard needs replacing. (I promise I’ve followed every guide and been very careful. I think I’m just unlucky.) I’m sick of fixing my printer. I just want a printer that works. I’ve decided it’s time for me to just upgrade.

1. What is currently the best consumer level printer available? I do NOT want a Bambu Labs printer. Otherwise, I would just get the X1C. Here are some things that are important to me:

• Open source software available (even if rooting is necessary)
• Very high quality prints
• Enclosure would be nice
• The bigger the better
• Reliable
• Ideally can be made quiet for overnight prints, even if I need to turn down the speed.

Currently I’m looking at the Qidi X-Max 3 and the Creality K1C. I’m hesitant though because both are new and both brands have had QA issues on other products. I’m also looking at the Rat Rig V-Core 3.1, but I’m scared it’ll be a mess of tinkering like my Prusa was.

Any input or recommendations from more experienced people would be greatly appreciated.

2. What should I do with my Prusa MK3S+? I don’t want to throw it out, but I’m not sure its worth anybody’s time or money if the mainboard and power supply are dead. I definitely don’t wanna put any more time or money into fixing it myself.

Sorry for the long post, but I felt adding context would help specify what I’m looking for.

Thanks in advances for any replies!
