I have used both, however I would rather buy most all my stuff from one place, at one time so the shipping costs don't kill me by puchasing piece by piece from multiple vendors. That's not saying I don't use pricewatch to find out what the cheapest price is for certain items, just to make sure I am not getting bowled over.
I like PriceGrabber much better than PriceWatch. I also use Amazon. Like leetemp I use them to check prices.
I usually wind up purchasing regular computer components from Newegg when they are sale.
I purchase hard to find items for case mods from specialty vendors online.
BTW - a little bit of nostalgia - A very long time ago when this web site was reviewing cpu's from vendors other than Intel and AMD, we used to check PriceWatch because it was the only web site providing a valuable service.
