We recently dumped DirecTV (thereby saving almost $90 a month). My wife subscribed to Netflix (something like $8 a month) and we access it through her Wii console. I'm in heaven - the Military Channel anytime I want, with no commercials. A caution though: if your internet service has any sort of cap on it, you'll quickly incur overage charges. A typical one-hour show is around 1GB.
I do have an antenna but it's too cold right now to install it. Attic probably won't work since our house has a metal roof.
