i personally have GeIL Ultra Platinum Series PC3500 CL2 DDR Ram, 2 sticks of 256. i bought them back when they were about 115 each, but you can get them for the same price as the TwinMos Ram, and they perform just as well as Corsair, and i've read reviews there they actually outclocked XMS Corsair Ram. But it's all up to what you feel like getting.
