Thought maybe someone can give me some input here. we have a Dell Dimension 2400 desktop. I want to install some more memory in it and called Dell and found out 512MB of RAM is $82.95 with them, free shipping. Now, I looked around on the web and have found a few sites that say they sell Dell compatible memory and these sites are about $20.00 to $30.00 cheaper than Dell, also with free shipping. I would like to save the money. Does anyone out there own a Dell and have you bought memory or other things from companies other than Dell? or, has anyone ever dealt with any of the following?: EdgeTech.com MemoryStock.com memoryX.net Thanks!
