Typically, good models will be $150-$300, the most expensive sytems can be $600+.  To maximize your speakers, look for excellent sound quality, with both volume and clarity. Likely, you will want something to integrate with your television and home entertainment center, so the remote control functions will need to be more involved to fit the entire system.

The better choices for these systems will be heavy duty and sturdily constructed, often with detachable speakers to optimize stereo sound potential.
