Just a little food for thought.
If your big concern is streaming Netflix in 5.1, keep in mind that the selection for streaming movies on Netflix, well, sucks. If you like reruns of TV shows, fine, but for movies, welll...
On the whole, I love our Sony 390. It won't do Netflix 5.1 but it will do 5.1 Vudu. I know, that's a different animal (no costto joun or monthly fewe. Justpau for what you watch) but the movie selection is far better. Sometimes, ya gotta pay for what you get.
As for the a direct rival to Netflix streaming, I'd say that the free seclections on Amazon Instant Video* is a better alternative as far a selection and quality and, as a bonus, it's cheaper and you get free 2 day shipping on Amazon purchases.
