Which is the best value low-maintenance enclosed 3D printer?

I have a BL a1 and a Prusa mk2s, but I’m holding off buying my first enclosed printer because I feel like a price war is brewing. I would love to pick up a large (300x300x300) enclosed printer for under £400-500 sometime soon but is this just wishful thinking? I need the machine to be very low maintenance and fast at printing.
