I can chime in for Matt since he and I went around this weekend (although I may be bias since I live here now). There is Coral Dynamics which is right outside of Charlotte which I like a lot because he sells a lot of frags for really good prices. Then there is Fins and Critters/FinsReef about an 40 minutes outside of Charlotte which sells a lot of really good high end equipment (H&S Skimmer, Bubble King, Tunze, etc) and have a decent selection of corals as well. There is also Fintastic which is a little on the higher side as in terms of price but every now and then you find the jewel in the rough type deal which makes it worthwhile to stop by. There are also a few other shops around but I dont really frequent them to often they are more fish then coral. All and all I have been happy with the selection so far.
