I am about to sell my old 3G on ebay, and I know they aren't worth a ton anymore but I'm selling it with 2 OtterBoxes and I bought it at the end of April so it's not old at all. What do y'all think a fair price is? Like I said I know it's not worth a whole lot but I was thinking about starting bidding at about $75 and setting a by it now price for like $150?
