I've just hit this discussion after finding this "pcbitcoinshop" myself, searching for feedback.
Similarly to topicstarter, I've found Canon 1DX Mark2 price to be suspiciously low: $3,794 - compared to ~$5,500 at other places.
So... Any development since the beginning of the month?
that's really not a suspiciously low price.
