I use the Obi202 and love it. No monthly phone bill, just a $70 box from Amazon. Not many folks have heard of it, but I did a lot of research after seeing the Ooma commercials during last years Super Bowl. The Obitalk products have excellent reviews and so far I have zero complaints after about 6 months of usage.
Roku, Netflix, and Amazon Prime have everything I want to see. Haven't missed cable TV for a moment and I'm saving a lot of money. Roku is amazing also!
