Fragglereef seems to go through good periods and not so good periods. Right now is a good period, IMO. Reefermadness usually only has cool SPS.
If you want rare acans you are most likely looking for rare color morphs, otherwise A. Hillae and A. Maxima are pretty uncommon right now. A. Lordhowensis is the most common species, with medium sized polyps and tons of morphs.
Another thing about Fragglereef - a lot of times they won' t have as good pictures as some other sites. So, while you are getting the same quality or nicer stuff, it may not seem that way until you get it in your tank.
