Haven't used them, but if you're willing to travel a little bit there's 2 excellent LFSs within about 5 minutes of each other up my way. One is Pet Shanty in Scotch Plains, the other is Ocean Gallery in Greenbrook.
I've done a lot more business with Pet Shanty - Charlie (the owner) is a great guy, very knowledgable, and very eager to share his knowledge. Shop isn't the most flashy and he tends to be a bit conservative in terms of the live stock that he gets in - but he makes sure everything is in good shape. He carries a ton of coral varieties as well, but all in smallish quantities.
Ocean Gallery has a tendency to get in somewhat more exotic livestock, and has a TON of coral bits in stock. They're a much larger shop - and while their supplies are excellent, I admit I get a bit of a negative vibe when I go in there (like they'd try to sell you something you didn't want or need if they got the idea you didn't know what you were doing). They also carry a ton of exotic fishes, some of which really shouldn't be in captivity (I've seen moorish idols in there on rare occasion...they actually tried to convince me to buy one at one point back before I knew better. Thankfully they were WAY more then I could afford back then).
Here's the links to both shops:
