Thanks. Yes, I'm going to forget it, at least until there is reasonable evidence that the 7D2's reliability has improved. With my 40D low light levels can sometimes make winter bird photography a bit of a pain, but at least that is a stable and predictable factor. Pity. I really do fancy the 7D2's better noise handling and higher ISOs, but the risk of getting a dodgy body seems just too high. Thanks to all those who voted on the poll.
