I purchased an iTouch from Ivan, and he insisted on renting a van and driving it all the way down from Canada to ensure I had it safely. I told him I would not be home, as my mother is very sick, and he made me fax him copies of her hospital bills.
Ivan is dedicated to the point of obsession with making sure you are happy with your transaction.
None of that happened, of course. He is awesome, though, and I'd buy another iTouch, or anything else, from him any day.
