Thanks for all of the kind words guys! I understand the gray market stigma, but in this situation I feel like we are unfairly a victim of some "clever" marketing by a competitor with a direct conflict of interest.
Nexus is distributed in the USA by Marine Camera Distributors in San Diego, one of our retail competitors. We gave them a shot a few years ago, but it didn't work out. I felt like I could offer my customers better delivery times, prices, and after sale service by importing Nexus housings directly from Japan. Due to an exclusive sales arrangement between Nexus Japan and MCD, we were forced to source housings from several Japanese retailers.
We clearly listed this in our online product catalog. We preformed all warranty service in house, or by shipping housings to our Japanese suppliers when necessary. MCD's statement about after sale service is profoundly incorrect, and would be disputed by every customer who has ever reported an issue to us with their Nexus housing.
We still offer Nexus housings in situations where they are leading housing, like the Olympus E3. For the latest Nikons they haven't fit in very well (mostly because of Nexus' omission of focus lock in an ergonomic fashion) and they've never really built a comprehensive port lineup for Canon, so we haven't done much with Nexus housings lately.
