MrDealio is a service that tracks electronics prices over time, informing you when to strike on the latest gadget. They've tracked the 60GB iPod for the past few days and found the price fluctuating between $368 and $399, a considerable difference.
The service is pretty helpful and quite cool—you could even do some economic modeling and watch as the price of product X rises and falls due to demand (High school students take note! Impress your teachers!). Strangely enough, they're not selling the 60GB for $299, a considerable savings.
