Well, you know, HP 7th will be out in a year , so you have enough time to think about it. I guess it's about 16€ for the english book, so even if it's not cheap, it's not so expensive. But I can't choose for you...Sorry.

You're right, you can't chose for me, and I can't chose before knowing what I'll have to pay the month it will be out ... so we'll see !
