DA Aquamaster:Yes there is, but the reason has more to do with marketing and snob appeal than suit quality. You can get as good a suit for a lot less money elsewhere.
I have to agree but maybe I'm biased after working for Abyss for three years. Hey to each his own...:54:
Looking at your choices I would opt for the Viking because of the repairability of the suit (providing you have glue and a bit of know-how). The only thing that can really Kill a viking suit is delamination of the rubber from the liner which is caused by improper drying and then mildew forming. Other than that you can cut them in half and glue them together again if you know what your doing.
BARE makes some nice suits as well ( I currently use an ATR HD) but they weren't on the list.
good luck
