Just a query to all you knowledgeable folk here on HUKD. How much should I be asking for a HTC Desire 510, Screen is perfect, body almost immaculate, the most minor of markings on the left bumper of phone, and the back case doesn't sit quite perfect on the lower right side. But it really is in excellent condition. Comes with original box and would be dispatched via 1st class recorded delivery. Any thoughts?
