I bought a Suunto D6 computer from Divetank a few weeks ago, and service was excellent. They are indeed a full-service dive shop and an authorized Suunto dealer; as such, they could offer the normal manufacturer's (Suunto's) North American warranty, unlike a dealer in grey-market goods. That was an important consideration to me in deciding from whom to buy. I called for a price. They called me right back. A few minutes later, my order had been placed, and it shipped that same day, via UPS 3-5 Day Service. They e-mailed me confirmation and a UPS tracking number. The shipment arrived exactly on time. The fact that Divetank is in Vancouver, Canada and I am more than 2,000 miles from them in the U.S. made little difference.
