You wouldn't buy a new car, or maybe even a new toaster, without doing oodles of research to make sure you're getting a good and reliable product for the money. Use that same consumer savvy this holiday season to make sure you're giving gifts that work and last.

I've gathered a collection of websites to help you separate the jewels from the junk -- without even setting foot in the mall. (I certainly won't snitch if you're using a "working" lunch to do a little research.) If you study up now before heading out to tinker with the gadgets, you'll be better prepared to resist when sales assistants try to talk you into flashy but unreliable purchases.

  • CNET. Another site for electronic reviews, CNET Networks' (NASDAQ:CNET) site also creates handy editors lists of their top five picks in each category. They pick AT&T's Tilt as the top cell phone, and the Canon XH A1 as the top camcorder, among many other examples.

An arm of the eBay (NASDAQ:EBAY) online empire, this website will give you an idea about how other purchasers feel about a product via consumer reviews.

  • Consumer Search. Can't get enough consumer reviews? This site, which is part of The New York Times' (NYSE:NYT) About.com services, surveys a broad array of consumer reviews, boiling them down to find a consensus for the top picks.
