Selling a Macbook Pro (mid 2009) - how much do I get?

Hi

I have a perfectly working Macbook Pro bought sometime in 2010 and upgraded the RAM, harddisk to 1TB & recently changed the DVD drive. Below is the specs -

Model Name: MacBook Pro (13-inch, Mid 2009)

Model Identifier: MacBookPro5,5

Processor Name: Intel Core 2 Duo

Processor Speed: 2.53 GHz

Number of Processors: 1

Total Number of Cores: 2

L2 Cache: 3 MB

Memory: 8 GB 1067 MHz DDR3

Bus Speed: 1.07 GHz

Graphics Card: NVIDIA GeForce 9400M 256 MB

I purchased it in Dubai and currently based in Bengaluru, South India.

Any suggestions will be a real help and highly appreciated.
