Price Advice Fair Price - Damaged 2009 Macbook Pro?

I was just wondering if anybody might know what the fair price would be for a damaged 2009 Macbook Pro. My computer's internet has been acting up for the past couple of months and, after having Apple look at it, I found out that it was going to cost anywhere from $600 to $1200 to fix. I'd like to have wireless back and figure if I'm going to spend that much, I might as well put the money towards a new or refurbished 13 inch MBP and sell the 15 inch one.

Anyways, I've been the computer's only owner since I get it new towards the end of 2009. It's unfortunately taken a couple of tumbles during the last couple years but it never had any problems until a couple of months ago, when the MBP suddenly stopped detecting the airport card and wireless internet. Apple's Genius Bar pronounced it dead soon after. A surprise victim of the trip was my battery, which Apple says is failing.

Other than the dead airport and sketchy battery, the computer is actually in alright shape. It's got some scuffs/scratches on the outer cover and a dent on the back, but it really is still a good notebook as long as you don't mind keeping close to a modem while you work. The specs are below though - does anybody have any idea of what a fair price would be for it? If I filled everything out right, GadgetValue.com gave a quote from $450-475, while Mac2Sell's was $520. I just wanted to check to be sure about price before I try to sell it.

Thanks!
