    Just have a demo of a Sim 200, great bit of kit. Better blacks than LCD and not so much grain. One problem the so called Rainbow effect, which I saw every time I blinked.

    Do all DLP's have this?? any mods to cure the problem?
    What is the best screen for a DLP?

    The HT200 is not the worst offender for this problem. 3 Chip DLP's never suffer from this problem...

    By using a six segment colour wheel and by spinning the wheel at twice the normal rate you refresh the red/green/blue fields much faster than normal making it harder to notice the rainbowing.

    The HT200DM has less than the HT200 and I felt the Sharp 9000 had even less than both of those. I believe the HT300 also has less as well.
