Newegg is probably the most popular site among hardware geeks. Pricewatch allows you to find to lowest prices by searching various sites, what you want to do say if you search for "Linksys Befsr41" on pricewatch. Look at the prices (note make sure on pricewatch, that the price in the column reflects the item you searched for and not an accessory, like in this case it would start with NIC's that work with the befsr41).. Then look on the right column to see what website is offering the deal. Use resellerratings.com if you aren't sure about a company. Also, check anandtech.com's priceguides and resellerarratings.
Here's a few I use.
Also, check out the forums at anandtech.com and hardocp.com , sites like that, to see what everyone likes.. good luck, have phun! ..
anandtech, sharkyextreme, 64bits, sweclockers, overclockers,gtek
