I just piked up a 32" Sony Bravia for xmas....Black Friday price was right at $488.
i personally like to stick with well known manufacturers Sony, Toshiba, Mitsubishi, and Sharp are pretty goog companies that make a good set.
If you are planning on embracing Blu-ray you will want to get a TV with a refresh rate of 120Hz....without going into the math it will give you a smoother picture and really take advantage of the blu-Ray technology.
Hit the internet and do more research....plenty of sites that will give you info. Another thing too....after you hit the stores and find one check Amazon for the TV, I've seen them upwards of $400 cheaper and with free shipping there.
I'm currently looking into a 50-52" for my downstairs.....
