Best budget 3d printer

Hi all, I currently have an old geetech i3 and I'm really tired about the fine tuning that she need for every print, i'm searching for the best printer under 250€ that can provide multicolor support (not immediately but maybe with an addon to be buyed separately), minimum 200mmx200mm bed size. could you advise something? I really appreciate expert advise as I'm little lost on the market now. thank you
