I've just come back from Currys in Selly Oak, Birmingham where they were selling off the Klipsch iGroove iPod Speaker System in silver, for £23.97.
Amazon currently stocks this at over £110. I wouldn't personally buy it for £110 but seemed like a good price.
Sound quality is good, and decent bass for a small unit.
I'm not sure if this is nationwide, but the label said 'Priced to clear' so might be worth looking in Currys if you're near one!
