Brazilians usually go for 150-400. It's the Hawaiian/Japanese dragons that are 800-1200. LA had a young Brazilian for 120 for a while, but it must have sold yesterday. I don't see it anymore. If you're looking online, MarineAquatics and LiveAquaria have them every few months.
Another eel to think about is the miliaris. They're not too shy, either, and are out during the day.
