Hi,
I've just got my D6 and am chuffed to bits with it. I had a prototype to play with for a couple of months, but this is the genuine article.
It is a slightly smaller, slimmer version of the 'bling bling' D9 better for everyday use, which is how I wear it (it is replacing my four-year-old Stinger) but it only has two gases instead of three, no air-integration and it is only depth-rated to 150m (think D9 is 190m or 200m).
For what I want out of a watch-style computer, it is perfect. It also has a better strap and buckle than the D9, and comes with a plastic protective cover and an extender strap for over a drybag.
In the UK it is going to retail for £470, and they are going to be in short supply to start with, so I wouldn't imagine any mega deals on it immediately.
Very nifty piece of kit, though
Mark
