How much would you pay for a PSP Go that...?

I have a Piano Black PSP Go in mint, 10/10 condition. I've only had it for 3 weeks. Got it for birthday and used it once then decided I didn't want it. It includes the USB cable, charger, manual, box, and PSP, all in their wrappers. I'm just curious what someone would pay for this because I'm about to put it up on Kijiji and would like to know what the price should be.
