I'd be real cautious with pricewatch...there are some dealers with VERY bad reputations that lower their prices a lot just to make pricewatch...and they screw a lot of poeple! Always cross reference with http://www.resellerratings.com
Cool site. Thanks for posting that. I do use pricewatch and you do need to check you vendors. For a while there were vendors that would list low prices, but would be "out of stock" until the price wasnt a bargain anymore. Paying with a credit card can really help those kinds of hassles. Cancel the order with them and let the credit card company deal with the scum.
