After much review of the threads on Hardforum I think I am going to go with the NEC2690, my question is should I spring for the SV over the standard model. The only difference I can find is the max h sync rate of 91.1 vs 119.2. I have also heard that the SV version also used a polorizing screen but do not know if this applies to the standard. Question is does the SV justifiy the difference in price and what truly are the differences. Thanks
