How does the JBL Creature 2.1 speakers sound?

I'm looking at getting a 2.1 set of speakers for my office PC... Ready through the threads, I'm leaning towards the monsoon mm-1000, but was curious if anyone has any experience with the JBL Creature 2.1 speakers.

Have you heard swans powered book shelf ($250), and cambridge soundworks (economical) ? Some of the best sounding computer speakers I've heard. You might want to hear them before deciding.

The creatures sounded ok but small. Swans will give you good music on your computer. Might want to upgrade the soundcard to something like yamaha cavit (ebay or units - usb connection improves the sound, unless you have an upscale soundcard like RME of Lynx.
