Lamplighter, there are lots of boxes that will stream Netflix. We do it from our Wii. Many dvd players now have it included. You might want to look around at what's out there. You may be able to get a box that plays BluRay discs and also does Netflix for around the same prices as just a Netflix box.
Also, I'm not sure what the terrain around you is like, but over the air broadcasts are better now than they ever have been. The digital signals are very strong compared to the old analog ones. If you don't have a regular antenna now, go to
http://www.antennaweb.org/aw/welcome.aspx and put in your address and then move the icon around on the map as needed to select your exact location, and the website will tell you what stations you can get with different antennas.
we have no cable, but with the antenna on our roof, we get something like 50 channels. with Netflix, and our recently purchased DVR, we have more viewing options than we need.
