www.pricewatch.com is more of a online parts bazzar. Where multiple online vendors display there wares. I totally agree whith what you said about 'you get what you pay for.' However my comment was about finding a part, and I still belive that if you cant fnd it there you wont find it. (have you ever been to the site and clicked on an item, and then seen how many hits you get, and the price range)
Although if you want the best RAM it' off to Crucial or Kingston.
