i like them because they are a good starting point for info on a fish (namely size adn food, i ignore their suggested tank mates, like mr v said, they often contridict themselves or give less than good advice onthat), but htey are great for pictures and give the scientific names (good to have for many fish taht have multiple common names or sharea common name with antoher fish). i would never order from them, i'd spend more inshipping than on the actual fish, but i like to use them as an additional reference and a jumping off point when i'm researching a new fish.
