I have to agree with one of the above posters about checking target. All of the targets around me have just redone their audio sections and are having great clearance deals on their old surround sound systems.
Last week, I got a NIB phillips with 5.1,progressive scan 5 disc changer, DTS, and some other pretty good bells and whistles. It originally retailed for $379. It was dropped to $299, then $208, and I got the last one for a final drop of $149.99. It is really a great system for the price. They had some other systems for some really great clearance prices, so check out your local target and see what you can find in the clearance section.
They also had a non-clearance 5.1 RCA system with DVD for $99.
