From memory, there are almost as many threads about their customer service (specifically warranty arrangements and what happens when things go wrong) as there are about their business practice. But in general respects, HDEW seems no better or worse than the other grey importers - the only significant difference being that they specifically have more issues around transparency of their business practices than, say, OSD. And unlike DR they don't pay to sponsor the forum.
The grey imports sticky has been a holding page since it was (somewhat pointlessly) opened, I suspect flagging it as a useful post is someone being ironic. Which would sum up the difficulties of developing an official forum policy on such matters whilst the forum continues to accept funding from one of the retailers in question. And this will continue to be a divisive topic until someone pulls their finger out and gets around to writing the official policy.
