I've been using the Pilsner malt regularly for about a year now. It has a very nice, clean flavor profile and the efficiency I've gotten out of it is great. I've used it to make saison, Belgian blonde, BDSA, sours and NE IPA. As an added bonus, it's significantly cheaper at my LHBS than all other Pilsner malts or continental pale malts.
ETA: They have crystal malts under the GoldSwaen name, and some of them do not say explicitly that they are crystal malts. It's a little confusing so I thought I'd throw that info in here as well. I've used the Goldswaen Red, which was wonderful, like a mix between Aromatic and Honey Malt.
