Want to know the sell price for my 24 inch monitor

Hi all,

I have a 24 inch Benq E2400HD monitor. Would like to know how much i can sell this for?
Its 4 years old.
Running like new. Everything is perfect.

Reason is i already have another Benq EW2440L and looking to buy another one of the same model for my multi monitor setup.


Thanks,
Rakshith
