Which price comparison site do you use?

Hi everyone..

Christmas is coming and I am planning to spend some money online for gifts.
I think many of us are, I just thought this would be a good topic. I have used
pricewatch.com but they seem to be going down the drain, the other big
ones like pricegrabber.com,nextag.com etc are all promoting whichever store pays them
the most, it is hard to really compare prices.

New startups are plenty such as www.PriceComparison.com, outsmarted.com, crazydeals.com etc..
but they lack the number of stores and products...

What do you all use?

Thanks
