With electronics, I find it hard to find a single site that does the job. Maybe someone else has a better solution, but I tend to use a pretty broad set of sites, and when I find a tv/computer/phone/speaker/receiver/etc. that looks good, I check it at all of the major sites and look for correlations.
Just using sites like cnet, amazon, online brick and mortar sites (like best buy), newegg, tigerdirect, etc. to compile reviews really helps. Also, check out AVSforum and at least skim the thread on any model you are considering.
I think it might be hard to pick a model this way, but I think this works really well as a well to decide if a model you picked is good or not.
Hope that helps a little. With the massive number of tv (and other electronics) manufacturers and types made by each manufacturer, it can be rough to find a good, all-inclusive site that really breaks down a large percentage of the market.
