I am trying to sell out two genuine samsung 1GB Sodimm memories which are installed in my 17 inch powerbook. I plan to buy a new iMac and to sell 17 inch powerbook. First, I sell each memory for $250 including shipping fee. I can sell both for $495. Please send me an email for any questions about the memories. I can show you pictures of the memory in my powerbook and a screenshot of system profiler.
