I have the $8.99/month no-DVD service for Netflix.
Be warned...the number of movies that you can stream from Netflix is about 1/4 of the entire Netflix movie library. And the library for streaming-only is somewhat disappointing. Most classics (Cassablanca, Ten Commandments, The Sting etc) are not available.
But I am using it to catch up on some good sci-fi that was on TV, and I’m watching the Ken Burns “Baseball” series and some of the old Mystery Science Theater series now (things I wouldn’t normally rent a DVD for).
If there is a new movie you want to watch, you can get it from Vudu.com. They have 24 hour rentals for about $4 each (more for XHD, less for stadard definition)
Yeah, I know. Lately I’m watching the Sherlock Holmes series from the 80s. Very entertaining and short enough to watch in one sitting. I’ve seen most classics I want to see. I keep the one DVD/month option just in case, but lately have not needed it. If there is a new release, I can always go red box (waiting for True Grit).
Add to that the fact that titles come and go. A title will be in your instant watch queue and then it will go to "DVD only status" and a few months later may return to "streaming available."
FWIW: "The Sting" is currently available for streaming. I saw it in the recently added movies list and added it to my queue.
