Ah, yes, I did pay a lot more than GBP100, but if you are willing to take a risk on a refurbished or second hand model, perhaps you can get them for around that? But I don’t know, you’d have to look around. Guess there’s a risk involved, but you pays your money and you takes your choice - the cheaper you go, the greater the risk, I expect.
You know, even a 32GB iPod Touch new from Apple is over GBP150 (at least here in HK), so less than GBP100 is going to be a stretch for anything other than second-hand, I am afraid, realistically …
