I really want to get a 2.8ghz macbook pro refurb. I am not quite sure if I want the 15in or the 17in because the difference in price is pretty minimal. But I will be doing some light gaming and video work i movie. I am just not real sure what to do with my 15in 2.16ghz core duo 2 macbook pro. Its in pretty good shape other than needing a new battery which I could pickup on ebay for less than $100. Do you think I could get $400 for this laptop on something like ebay?
