how much is my laptop worth

[Mark Shakes]

I have a Toshiba Satellite P500 PSPGSA-11S003 and I was just wondering what the approx market value would be for it.
I have been flexirenting it and they would like me to put in an offer for it. Any advice would be appreciated.
Cheers

Rule of Thumb - Take your cost and then subtract 10% .... then 5% for each month of age for 6 months (60% value at this point) ... then 10% for every 6 months thereafter.

1 day old = 90% of purchase value
6months old = 60%
1 year old = 50%
2 years old = 30%
3 years old = 10%
