If your don't mind assembling the printer yourself, get a Voron 2.4 kit. It's an open-source 3d printer, perfect for getting your hands dirty. Much easier to upgrade and repair than a Bambu.

Edit: I believe Voron printers are typically used over a network, but you should be able to just plug a monitor into it and do the slicing and printing on it directly. They typically have a Raspberry Pi or a Pi clone built into them for running Klipper.
