I heard the kingston pc3000 overclock quite well they are 59 dollars a 256mb stick @ newegg right now. I THINK they might be BH5 (could be mistaken), but in either case they overclock wonderously. That would put them righhhhht where your budget needs them to be free shipping on them too.
: Zipzoomfly has the same sticks for 56 bucks a stick, also free shipping... hehe. If counting tax then.. should be about 120 bucks give or take 1-2 dollars. Nice eh?
Kingston HyperX Series Dual Kits 184 Pin 512MB(256MBx2) DDR PC-3200 is going for $123 @ newegg and from my understanding BH-5 running at 2-2-2-6 and very good for the $$$. You'd want to get the non-A kit.
