I got a couple of Corsair OEM (256 mb) sticks at outpost.com for right under eighty dollars. I called outpost and was told the memory comes with a lifetime warranty. Plus, adding the antec sx-830 to my order push the total over $99 and will provide free shipping. Finally, before doing the order I signed up with fatcash.com and I'm hoping for a 2.4% rebate on this purchase.
A little good news! I checked over at pricewatch and found generic 1 gb ddr 2100 sticks are selling on the net for under four hundreds each.
