No offense to local shops... but you're probably not going to pay less than either buying from a fellow reefer (such as Steve here) or on the used goods forum. At least, that's been my experience from my own price shopping.
You definitely should try Exotic Fish and Coral in Milford though, if you're still living locally there (further South, I have additional recommendations, as I'm sure others do). They are really awesome! Just bought a few corals from them over the weekend and they were most generous. Wish they were closer to me!!
