I was looking to buy one second hand, but now I'm not so sure. I don't plan to use it as a primary device and it will be only for testing.
Reading this thread there seems to be some of those floating around, but the price is just too high considering that I could get a new one for 470 pounds (that's 20 pounds more than second hand for a new device )
I'm sorry ppl that are trying to sell are fundamentally competing with the indiegogo campaign.
Perhaps after it will be easier.
