Was just going to ask the same thing.

prusa mk4 fully assembeld

https://www.prusa3d.com/product/original-prusa-mk4-2/

it does z bed leveling fully automated

and you get always perfect prints

if you have a lower price target

you have to maybe tinker sooner or later

I had a prusa Mk3 and it worked really well. I miss it. It was expensive though. Haven't tried mk4 but it's probably even better.
