DS2 has a Sharp phone he inherited from his sister and he has managed to "lose" the charger (it may well be in our house somewhere but the chances of finding it are not high) - so we look on ebay, naturally, and find a brand new one for £3 delivered.
I know it's not perfect, and things do go wrong, but if you want anything you can't stroll into a High St shop for it's just magic. (We have a very well-used well-loved ancient Monopoly set, which all our kids love to play with and said they wanted to inherit , so last Christmas I got them an identical set each )
