How much would I get for my CD player?

I want to sell my CD player with a built in iPod/iphone 4/4S dock and radio but the radio doesn't work as the ariel is broken. How much would I get for it?

You will need to break into someone's house and leave it there for someone to take it.

Good job not saying just what brand and model you have. Well as good as anyone's guess is that it is some el cheapo one. You will get NOTHING for it as these players are disposable and hold zero value. You can't be that desperate trying to sell at broken player. Respect yourself.
