Greetings from a former resident of Oswego/Boulder Hill just "down the road" from you. It has been a long time since I checked out the reefing scene in the Aurora/Naperville area, but I can tell you that compared with what used to be there, you are in for a real treat here in Tampa! You have so many good LFS's in the Bay area, and the Tampa Bay Reef Club here is simply amazing (and unbelievably large in number given Tampa's population). You can purchase much of what you are looking for in setting up a larger system as well as coral frags/livestock from club members for a good price, and there are LFS's here that are very competitive with online prices. There are also many opportunities, both locally and down in the Keys, for collecting livestock. You also have a number of great public aquariums here (none quite as big as the Shedd, but very nice none the less): Florida Aquarium, Orlando's Sea World, St. Pete Pier Aquarium, Clearwater Aquarium, Mote Marine Laboratory in Sarasota, as well as first class research going on at University of South Florida's Oceanographic Institute. Do look up the club when you get down here, and welcome aboard!
