List of 3D printers, with their pros and cons. You can just skip to "Top Picks"

You can fiddle with the settings as much as you want to fiddle with it. I use the Sovol SV06+, and after assembly (which you can't go wrong with because it's just near impossible to place things the wrong way), the prints worked just fine with PLA and the default profiles in the Prusa Slicer. You can leave it like that, but if you enjoy building, you'll enjoy fiddling and starting to explore things like different materials, settings, etc.

Also, what and how are you planning on printing? Are you making your own models or downloading them? You will end up having to fiddle with models regardless for printability (for example, printing something tall and thin will result in fail prints in many cases).
