The Bottom Line		Priced less than a midsize flat-screen LCD TV, BenQ's MP512 ST DLP projector is a solid, affordable option for people who want a big screen for casual use or gaming.	The new chip in Samsung's SP-A900B helps it to outperform every projector in its class, including its step-down Joe Kane-designed brother, and to compete favorably against significantly more-expensive three-chip DLP projectors.
