Where can I get some decent PC2700 for a reasonable price? I want to get two 512s and I'm seeing prices in the 58-60$ area, but when I go to buy it, they're trying to upsell me by saying: "This is generic memory, it's CAS 3, 4-layer, can't guarantee compatibility blah, blah, so get the "good one" for $80 per DIMM. Well at $78 I can get Crucial. I don't know much about RAM and all these specs seem b.s. so they can upsell me. I have a Dell Dimension 2400 2.53 GHz with a 400 FSB. The different sites say that I can't use CAS 3 with this system and that theirs 6 layer, instead of four layer blah, blah. Heeeeeelp!!!!
