Ravedood, it would be helpful if you let us know what kind of corals you would like to keep versus what kind of lights you have so we can make sure what you get will survive.
Of course softies are going to be the easiest (and usually the least expensive) to keep in the beginning, followed by LPS, certain SPS species (montis, birdsnest, etc.), and ending with the more light demanding of the SPS species, clams, and some anemones.
