Where can I buy used Nokia 7510?

Hey I am using Nokia 7510 from past 1 month and believe me this is a great phone and for sure you will gonna love it. I amusing it from last 1 month but still till now I have not faced any problem with this phone. There are some special features in this phone and I hope you should know them before buying it. So I am giving a little brief about this phone. The Nokia 7510 has a brilliant display, good call clarity, and a midrange feature set that includes Wi-Fi. The 7510's external display is its most eye-catching feature. It is invisible when the backlighting is off, but the clock has large, bright numbers. The keypad is spacious and with a distinct separation between each key. Yet, the buttons are a little too flush and slippery for our tastes.
There are many websites where the sellers give the advertisements to sale the phone so I think you should search on these websites as you want to buy a used phone and the websites are: mobiles.sulekha, olx.in, mobile88 and amazon.
