It took long enough but I finally used the Suunto D6i I bought in the Florida Keys last week. As I don't have a console and was relying on the wireless transmitter for my air, I have to admit that I was worried. But everything worked great! There was an issue when I switched my gear to a new tank as the watch kept saying no connection. After 5 minutes of searching through the menu, I cleared the pairing code and it worked great. However after that small issue, I now plan on buying an inexpensive console as a back up.
So to others looking to buy from Mareshop.eu, I'd recommend them. I actually plan on buying the console from them since they do seem to have the best prices in my area.
