You could try someplace like Computer Exchange for a legit second hand one... But I am betting they'll still be quite a few hundred quid. People don't think about how expensive these are as devices till they lies or break one - I didn't realise until my Dad dropped his in the loo a couple of years ago. That's why the contract is the contract and you have no right to terminate early without penalty - you're effectively paying off a loan for your device. He claimed on the house insurance, only a £50 excess. Probably your best option.
