Hi Guys, Just thought I'd ask for advice on selling my MacBook Pro (wanting to get a Macbook Air). It's the mid 2009 model, however since purchasing it I have upgraded the memory to 8GB using Crucial Memory. I have also put in a 500GB hard drive. This week, seeing the warranty was due to run out at the end of this month, I took it into the Apple store to see if they would fix a few issues I have had, they put in a new battery, a new trackpad AND a new disc drive. My question is, how much should I be asking for this laptop? It's my first Apple laptop so unsure of the going rate for this model. It has a few scratches on the back and 2 of the rubber feet have fallen off. Could anyone help me out with an estimate?
