I asked my contact at a Canadian retailer (the largest pro audio retailer in Canada) and he said they could get the DPA 4006a in about two weeks. I was surprised, given what I heard from my Danish friend, but who knows, maybe the Canadian agent has some in stock. Here is the contact info if you want to make a further inquiry with them. He quoted $2,845 Canadian each.
Marc-Andre Demyk is my contact there. You can talk to Francois for now, Marc-Andre is away until March 7th.
