denon, if you're interested in a 2.1 setup, you won't beat the Klipsch ProMedia 2.1's. I recently ordered a set from outpost.com, and they arrived the next day. I replaced a Boston Acoustics MicroMedia (now called BA790) 2.1 setup, and the Klipsch PM's blow them away, both in sound quality and volume.
If however, you want a 4.1 setup, then you should consider other options. Right now the prevailing thought of most on the forum is the Boston Acoustics BA4800, which you can pick up for approx. $150. I would avoid the original Klipsch v2.400 system, as it had some issues (out of production now, but still floating around out there ). Klipsch replaced the v2.400 w/ the 4.1, and that's selling for approx. $300.
