Go to Radio Shack and ask them if they have any discontinued laptops. They will never be advertised though, so you need to be persistant. Also, go to a RS in a strip mall. Those people will often go out of their way to find you any computer you want. Because the "strip stores" don't get many computers in their inventory, so the more they sell the more they recieve in their regular shipments.
My laptop retailed for $1300. I bought it 4 months after it had been discontinued and I only paid $900.
I used to work for Radio Shack. This is kind on an inside secret so Shhhhh.
I also got my surround sound reciever for $40. It origionaly retailed for over $500.
