Go for it, my Emperor is still going strong. He's a good eater too the only thing is I can't get him to eat different things. He's stuck on eating one thing, which I'm not sure how to deal with it.
But yeah I'd say go for it, Saltwaterfish.com takes really good care of their fish and other live stuff well it seems. Flame Angels are very nice.
Stingrays are the best!
