I need some advice on a entry level system.(speakers and reciever). Last week I bought a 50" Hitachi LCD Rear Projector so I want to get a surround system. I really know very little. I plan on doing some searches on the forum. My room is 22 x 12. I have a a Progressive scan DVDand I also have Dish Network and I have a HD reciever on the way. The only thing I have that may be useful is a set of Baby Advent speakers. Any suggestions on a decent entry level system. I have not looked to see what available but perhaps in the under $300 range if thats possible
