I'm fairly sure I'm going to buy a new Chamonix. Though I'd love to shoot some IR, I don't have any and can likely come up with a temporary fix if I ever get some (and it's down to one or two versions anyway). Other than that, I haven't heard any reasons to not get one and I think any other differences are so small as to not matter. It comes highly rated by those who have them (and they rarely come up for sale used, so I'd believe those who have them want to keep them).
Thanks all for the input! I hope it all helps anyone else who finds this thread.
You could always put up a WTB over at LFPF. There's always someone leaving the format.
