Flat Screen TV

So I've been thinking a lot about getting a flat screen. Sony, Samsung, and Sharp all look like good TVs to me, but honestly I don't really know which reviews to trust. I've found the Samsung LN-T4065F. I've been to a couple stores, but haven't found this particular model in any stores, but the LN-T4061F looked pretty good. Has anyone had experience with any of this? Any advice?
