"Well, Crucial's ought to be the best right now. "
Actually, the Crucial PC2100 DDR is only Cas2.5 now, the Corsair PC2400 uses Micron Cas2 modules that hit 165+. When Crucial sells out of the 2.5 stuff, they will start replacing it with the better Cas 2 Micron chips...in a couple weeks or so. The Corsair is a bit pricey..~$100 for 256mb.
