Price Advice Value of my mac?

Hi,
I was just wondering how much you would consider a fair price for my macbook pro.

I intend to sell it some time around September-November 2012,probably on ebay unless there is a better place to sell and I'd like to know a rough ball park figure of what I can expect to get.

Mid 2010 Macbook Pro 13"
2.4GHz Core 2 Duo
Snow Leopard OS
Includes original packaging and startup disks etc.
In perfect working condition.
Some cosmetic damage: Very few light dings to the casing on the back of the screen. These are almost unnoticable. Fairly large scuff on the front right corner, the case is aver so slightly dented and the corresponding corner of the screen is slightly misshapen. (The case around the screen not the screen itself) The front left foot has come off but I still have it. Could be fixed with some double sided tape.
The original hard drive is 250GB, but for slightly less or more respectively I could replace with 160GB or 500GB HD.
I will supply the computer as new so you will have to install the OS etc. unless specified, as I have some software such as iWorks, Aperture, VMWare Fusion, Reason 4 etc. which might be desirable.
Finally at the time of selling there will be about 10-12 months of applecare left.

I'm hoping for at the very least £200. If I can expect less than this I doubt I will sell. Would love somewhere around 400-600 although that is unlikely.

Any thoughts?

Thanks in advance,

Matt
