I like Circuit City's reviews. They are customer based and this way you get a good feel about what other people think of the product. Sometimes there aren't any reviews for certain products though.
My friend has a 32" Sony Wega and it supports 720p and 1080i. I'm not sure if it has HDMI hookups, but I saw one up at Best Buy for around $850 a few weeks ago. It has an amazing picture, but no widescreen. :(
