eCoustics is a site that compiles reviews from a lot of different sites in one convenient location. Here is a link o their
HDTV Reviews.
They also compile useful articles and buying guides. It may take some time to weed thooght all of the info, but at least it will all be in one place. Their focus used to be strictly A/V related, but in the recent past they've branced out to include a lot of other CE products as well.
