I don't fall into the 2011 bride group, and it's been a while, but I also got my dress at Anderson's in Anchorage. The prices seemed reasonable, and the dress materials didn't seem super cheap.

In the lower 48, I have known several people who had good luck at Davids. I'm not sure if the selection is somewhat dependent on the year, and the specific store location (my gut tells me yes), but they were all pretty pleased with their dresses.
