Just my '2 cents' - I don't think it is worth going SDI anymore. I had an SDI modified Denon DVD player passing 480i to my original Lumagen HDQ. When I upgraded to the Radiance (which most annoyongly did not have SDI in) I went out and bought the Oppo 980 so that I could send 480i over HDMI. I think that 480i over HDMI is just as good as 480i over SDI, and the Oppo player is less expensive than the SDI mod.

I did spend some time and money exploring the various SDI-to-HDMI adapters, and althought the Lumagen one may perform better, I was not happy with any of the ones I tried. Plus, again, the Oppo player is almost certain to be cheaper than the Lumagen SDI converter. IMO, SDI has had its day!
