$299 for a Sony W600B (40"). It's only a 90 day warranty, but I took a chance on it around XMas, and I like it, and I've had no troubles at all.
I think the input lag is around 33ms.

RTINGS give the Sony an 8 Overall Score, and the LG a 7. But this is a refurb. I kept my box for a couple of months to make sure everything was kosher, and it works perfectly. But I know some folks don't take chances on refurbs. Maybe I got lucky, but it is a pretty good deal.
