Hey Gerry, here's my do-it-on-the-cheap-but-effective idea.. Many Sony TV's still provide an analog audio output with a fixed/variable choice that you can assign from the TV's menu. On top of that, many Sony sets also have SRS-WOW simulated surround processing built in. If yours has it, you should see the little SRS logo on the TV somewhere. SRS processing does a great job of simulating surround with a pair of stereo speakers.
All you have to do is feed the "aux in" of a small bedroom stereo using the fixed setting, or feed a nice set of powered speakers using the variable setting, and enable the SRS mode in your TV and you should have very decent simulated surround without spending $500 for the Polk, Yamaha, et al..
I have an older Sony V series 27" tube in the spare room connected to a set of $79 Cambridge Soundworks "Soundworks" speakers (two small cubes and a small powered sub) and it sounds much better than you would expect for the money and it has high WAF!
