I know you said something around $25, but I would save your money and keep your eye opened for a good price on a Logitech Z5500. You will not be disappointed. I have seen this package for as low as $199 for a re manufactured system. I unfortunately purchased mine about 8 years ago for $399, but I feel that I got my monies worth. It will produce 500 watts RMS into 5.1 channels, has a 10" sub, it is THX certified and will decode Dolby Digital and DTS.
