There are so many different variables when picking out live rock, it would be best to decide what kind of look you want, how much stuff you want on it (hitchhikers), how much you want to spend, etc. If you want the best, there are some places with really good looking live rock, in terms of colors of coralline algae and hitchhikers like macro and corals, but it will cost you. This includes places like Tampa Bay Saltwater, and Dr. Mac corals, and anywhere you can find walt smith premium LR. If you want the best "deal" in terms of price, the rock probably wont have much on it, and wont be too colorful. The pacific rock has a much different look than the caribbean stuff, though I don't know what TBS uses as its aquacultured rock, it might be just limestone. But haiti and jamaica LR is basically dead elkhorn coral. With the pacific stuff you can find pieces that look more like actual rock as opposed to dead coral. Then there is also branch rock, and other coral-like shapes available. If you are looking for middle of the road LR in terms of looks and price, I like exoticfish.com, and I have heard mixed reviews about liveaquaria.com. I have ordered caribbean LR from etropicals.com, it was pretty cheap, but pretty plain looking. But if thats all you want it's a good deal. Check out diff sites with pics and once you have a clearer idea of what you want someone might know a good place to order it from. HTH
