Unfortunalty since you have no sort of warranty there isnt anyone who can really help you. Apple sometimes buys back ipods for scrap at least at the Apple store near me. If it is still under the 1year MFG warranty I suggest opening up the unit and cleaning all the corrosion off the unit and sending it in. Just make sure that it looks the same is when you opened it up. I've heard of many people getting the warranty voided from not putting it back together correctly.
