The Ender 3 S1 Pro is pretty popular at my store right now, I've put together a few of them and as long as you check to make sure the gantry is level with the frame and that all the wheels are tightened correctly, it prints pretty solid. If you can get a really good deal on a Ender 3 Pro or Ender 3 V2 though, they're still not bad either and there are tons of guides on how to mod and upgrade the machines. And if you have a Pi or SBC lying around, definitely give Klipper a shot once you're used to the machine a bit, I put it on all my machines when possible now.
