The Sim2 ceiling/wall bracket kit works with all the single chip models.
It's a very versatile kit allowing you to have the projector anywhere from close coupled to 1.25m from the ceiling. Can also be used for wall mounting the projector.
They cost about £150
I used a Unicol ceiling mount with my Domino 20, as the projector was white I was able to have the Unicol powder coated in white to match, looks better than being painted white by hand or sprayed white from a can!
