Would that be this one?
I actually could check this year's LG 42" myself, which is also a 60Hz. I don't like its scaling of SD material at all (blurry damn mess, and when you turn the blur off, a pixelated damn mess; at no time do you get the correct aspect ratio, either) but it does pretty well with Blu-Ray and DVD. There is something about the way things look on these sets that I don't like but that's really not a matter here. I should check that out and get back here with my thoughts.
It's a bit frustrating, honestly, to try to give any recommendations like this because one never can be sure how the input lag or quality will be from one system to another. It does sound as if it has a low input lag, but its performance with native resolution doesn't guarantee that picture quality or low lag with other sources.
