Qidi X-Plus 3. If it's anything like my Max 3, which is the bigger version, it ought to be plug in and use (after running the included calibration). It's on "sale" right now for $500, but it's always on sale. It's also not made by Bambu, and if I were you or anyone else I would not give one rusty penny to Bambu for anything.
The draw with this thing is it comes with a fully enclosed chamber with a heater and PID to control it, and it's the easiest time I've ever had printing ABS and PETG if that's what you want to do. You can slap a 0.2mm nozzle on it easily enough if you want to print tiny stuff.
If you don't care about high temperature materials you can get the X-Smart 3 which is based on the same system but is smaller and minus the heater, and is even cheaper.
