If you have Ethernet connectivity in your living room, the smart move is to go with an entry-level Blu-ray player. Most such players available in 2010 offer much of the functionality of step-up models, minus built-in Wi-Fi.
That's the case with the LG BD550 ($150 street), which is nearly identical to the step-up BD570, except it lacks Wi-Fi and DLNA compatibility and costs about $100 less. If you can live without those features, the BD550 still delivers excellent image quality, relatively speedy load times, and a generous suite of streaming-media services, including Netflix, Vudu, Pandora, and YouTube. It's missing the expandable Apps platform of the competing Samsung BD-C5500, but if you mostly care about core streaming services, the BD550 is a solid entry-level choice.
