Without the AMS, a Prusa Mk4 (used?) You're always going to pay a bit more but they're European built and extremely repairable. Unfortunately you do need to pay for the Mk4 or Core to match Bambu's ease of use. The Mini is also great for occasional use if you don't need a big build volume.

The Mk3 is also easy, and can be had for cheap now, but it doesn't have auto Z-adjust which is really nice. It's also noticeably slower compared to the latest models.
