No chance in hell will I be buying those Dyson ships. Way too much for too little return. I've purchased a few ships, but never a three-pack. And yeah, the material on these ships is not nice. I have a feeling that they will not sell well at all. Only the die-hard collectors who have to have everything will be realistically looking at them.
I did get the free ship, one of each version, and will probably use it regularly on one character.
Oh, and I have to say that the mirror heavy cruiser is a surprisingly good vessel. I picked one up off the exchange for a Fed engineer I was leveling, and have really enjoyed it. Didn't use the Constellation saucer--I didn't think it went with the other parts very well in the ship tailor. Gone now, of course.
