Samsung HL-S4666W 46-Inch DLP HDTV
Excellent television
As others have done, I pondered over which format to get - LCD, Plasma or DLP.  I made a solid choice.  DVDs look phenomenal on this television.  The big benefit over DLP or LCD is you do not notice any pixels or screen door effects.  As far as rainbows go, I don't see this effect at all.  Color saturation is pretty good.  Digital satellite tv is hit or miss [SD really] depending on the program source.  I am going to buy an off air HD antenna as I have heard they are great.  Very happy.  Samsung makes a great television.
