Multi Colour / Multi Material 3D printing

I’m on the market for a multi colour 3D printer.

I was wondering what experience you guys have had with the options out there.

I’m tempted to wait for the new Creality K2, but nervous of being an early adopter. I want a large build plate (I don’t think 256x256 is really enough), and I don’t want anything that creates a purge block as it loses too much build area.

Any experiences you can share would be much appreciated.
