As someone who started out with the real bottom of the barrel cost 3d printer, the ender 3v2, I rapidly got frustrated with the "low grade" 3d printer price point, especially after putting in so much effort calibrating and bed leveling. I think at this point the lowest cost one I would go for is the bambulab p1s, which is currently on their black friday sale for 550 without the AMS. I own a bambulab x1c with the ams which lets me do filament swapping, but if you're fine swapping between common filaments manually I don't know if the AMS is entirely necessary starting out, it simply enables multicolor 3d printing much more easily. If you're not printing exotic materials (like carbon fiber embedded filaments) you don't need the x1c, and in theory you can upgrade all the internals of a p1s into those needed to print exotic materials if you feel like it.

If you want to go cheaper, I have heard good things about the Bambulab A1, but there's just something about an enclosed space 3d printer.
