I currently have one small 30 gallon saltwater setup w/ a 10 gallon sump, but I have 4 other freshwater aquariums, and I have to say I enjoy the saltwater more than all the others combined. I have been keeping freshwater for 20 years or so. My 60 gallon African Cichlid tank is the only one that I really enjoy other than the saltwater because it is really dificult to get teh right fish together so they don't constantly fight. Here is a pic of it:
