I usually do a google search for the item + "review." Usually the first hit is epinions, which I check out for user opinions. Then I look for hits that are forums pertaining to that type of product for more user reviews. Sometimes I'll check out amazon and cnet user reviews as well, but most of the people on those sites who give a product a negative rating are just morons who couldn't figure out how to use the product correctly.
For editorial reviews, I check out whatever big sites dedicated to the product at hand google pulls up for me.
Finally, I check anandtech forums!
