I think the most critical factor in selecting a 3d printer is the size of the community of users and the availability of parts. I have used many different 3d printers, done many printer modifications, and keep returning to two brands that I find cost-effective with good communities and good part availability. Creality and FLSUN. Unfortunately, since Creality has so many different machines, you have to be careful. Some are excellent. Some are overpriced and perform poorly.
