I recently purchased an iPad Air 2, so I'm selling my 1st Gen. 32GB Space Grey iPad Air. It was purchased exactly a year ago, and is in excellent condition, with no issues whatsoever. I wouldn't be including my smart cover (keeping for Air 2), but otherwise it comes with the charger and all original packaging. How much do you think it would be reasonable to ask for it? Note that new, in Canadian Dollars, they're $489 (~552 incl. tax). Thoughts?
