Hate to break it to you but I was just on newegg looking for your ram (PC2-6400) and the 2x4gb ram sets were in the mid triple digits ($150+). So I don't think you can find it under 80 dollars, its laptop memory so it is way more expensive than desktop memory. In addition, it is DDR2 which is more rare to find these days and if you do find it then it will cost 2x-3x more than DDR3.
