Pricewatch is good, but make sure you check the validity of the vendor before using.

Also, you'll often find that Newegg is top10 on those lists anyway, and thats why I stopped using Pricewatch.

To research your parts and other gear:

www.anandtech.com
www.sharkyextreme.com
www.tomshardware.com

And a fave for reviews without alot of technical jargon:
reviews.cnet.com


For buying parts:
www.newegg.com (no-brainer)
www.zipzoomfly.com
www.monarchcomputer.com

End-User accessories and retail gear at:
www.cdw.com (they normally charge a little more, so I wouldn't necessarily get parts here, but their customer service is second to none).

Should you find a questionable site (i.e. Billy Bob's Shack Pooter Parts), check it on www.bbb.org (Better Business Bureau). If they're not listed, it's generally best not to chance it.

Cheers!
