well, there are a ton of reef safe fish out there that are amazing, spotted anthis, or most of the anthis breeds, tangs, clowns, blue throat triggers, coral beautys, firefish, rabbit fish, wrasse's, i could go on forever, but you get the idea, and the neat thing with a reef is, if you get in with some of the marine clubs you can get all the corals you want alot cheaper than dealing with a LFS. the main differences are lighting, and nutrition really. other than that FOWLR and Reef tanks are verry similar, not to mention when you get into the reef safe fish, you are alot more likely to keep cool critters like starfish, shrimp, crabs, snails, all the stuff that makes a symbiotic relationship and reduces the maintinance on a tank.
not to drive traffic away from this site, but reefcentral.com is a great site for information, along with reef2reef.com, check around you probably have a marine club close to you that has a site also.
