I've been to Jeff's, and have no complaints. He has an awesome business. Great selection, great prices.
I haven't ordered from his site, but I can imagine that if what you want isn't in his outlet store, you can order it from him.
Of course, if ordering from a site, you can always do so from SWF as well...(like that plug?) heh heh...
Scales and Tails in Burbank has awesome Live Rock. Pasadena Tropical Fish (in you guessed it...Pasadena) has a nice fish selection. The owner knows what he is talking about too, which is nice.
