Greg wants to get a sound bar for his HDTV and wants to know which would be best to get. Powered or non powered? Leo says ultimately it doesn't really make a difference. Having said that, what Greg has to consider the "spousal acceptance factor." A powered sound bar gets it's power from the TV, while an unpowered sound bar will require a receiver to power it. So he should buy a powered sound bar.
Leo recommends the $700 Sonos Playbar. The $2500 Bose Sound Bar is awful. Sonos also has a system so he can listen to internet radio and more. It'll work with his TV remote control.
There are cheaper ones, but they're basically just a rack of speakers that are only marginally better then the TV speakers. Other good options include Polk Audio and Vizio.
