So I will upgrade, whee!, but need to sell my old MBP as I don't need two and am partly strapped for cash if I don't sell it. I'd like to keep two, but one would just collect dust, and I tend to buy extended warranties in case I end up with a lemon (for anything with a LCD panel or gets warm with usage, I will splurge ). She's a 17", mid-2009 model in near-perfect condition. Assuming I take out the upgraded RAM and put it back to the original 4GB, DealTree will give me $634 for it. (they see the extra 4GB as being value-less). Is DealTree a ripoff for their customers? Thx!
