Getting the latest in cutting-edge consumer electronics doesn t mean you have to pay full price -- especially not these days.

Electronics sales fell 10% in March compared with last year, according to the National Retail Federation. The drop was just the latest in an eight-month-long string of year-over-year sales declines that has forced many retailers to slash prices in order to clear their shelves, says Larry Chiagouris, a marketing professor at Pace University s Lubin School of Business in New York City.

But hunting down deals for gadgets is much more involved than finding a sale on chicken at the supermarket. Electronics retailers tend to carefully control their sales rather than blanket shoppers with storewide 20%-off coupons, he says. Consumers are also more particular about what they're looking for than they are with other purchases. (They aren t just searching for a computer, for example, but an HP laptop with a 15-inch screen and a 160GB hard drive.) The category is such a sophisticated one that people cut to the chase and look for the lowest price on the exact item they want, says Chiagouris.

The best place to start that search: online deal-hunting sites that focus on finding the latest sales and price cuts on consumer electronics.

Here are four sites that SmartMoney put to the test:
