Okay, I'm "playing with it now, or just was a little while ago but after doing some research found out the the Roku 2 is just as fast as the 3 and cheaper, got mine (refurbished) for $50. Also picked up a digital (amplified) antenna, $25 shipped, just tested it out, get 65 channels, granted 2/3s of them are in Spanish....... but I get all the local stations and it's just as clear as watching it on cable and the antenna is currently lying flat on top of the TV cabinet, not even mounted to the wall yet. Sure I have to switch input on the TV but that's just one button and a couple of clicks to select which input I want.
Still have the cable for now until I get used to the Roku and set up my channel preferences.
