How much is my xbox 360 worth?

It depends on how old the xbox is. If its a elite or the newer slim then its more. Also the older "pro" console isnt worth as much as a newer white console considering the red ring of death (i know it may not have it now but its still prone to getting it). But if i can tell you anything its DONT SELL YOUR CONSOLE AT GAMESTOP/EB. you will get less im positive. As a loose guess id say 100-150. That disc problem can really affect the value considering a fully functional xbox used is worth 150.
