I went for the brand new one.
I ordered it yesterday afternoon and it arrived today! At first the estimated shipping date was
Febuary 2012 due to an out-of-stock printer, so I phoned and changed it and in a couple of hours I received an email to say it had been dispatched.
By the way, for some reason I thought that Apple had stopped doing the free printer for students so I was glad to see they hadn't. There is also an extra 3% (before VAT) cashback available using quidco. So that's a £70 printer, plus the £25ish cashback, plus the £65 voucher, plus the HE discount, PLUS the free extended applecare - it would have been crazy to not have got it new from apple.
...And they say romance is dead.
