Its hard to suggest anything other than a PS3. It does so much more than just play BD discs and even if you dont think you'll use the extra features, you will....trust me! I said I would never play games or download games from the PS store. Sure enough, I have and will continue to do so. The wireless firmware updates are sooooooo cool.
The PQ and AQ are also excellent and compare favorably with ANY stand alone player.
