For simple image alignment, a Peerless PRGS Series Projector Mount is the best choice. The precision gear design of the mount ensures exact pitch and roll image positioning. Its excellent design needs to be set and then you forget about it all, there is no need for adjustment screws or micro-adjustments. It can be positioned at the desired location either by simply turning two adjustment knobs with a phillip screwdriver or by extending the knobs to adjust by hand.
