Or if you have the money you (and this really depends as memore says on what you classify as old school and what genre of dance you are interested in?) get hold of any early Sasha & Digweed stuff which has all been deleted now but i think still sounds fresh and has for me stood the test of time and is out there on ebay etc , thats assuming it is a mixed compilation Cd you are after. Or the Global Underground series are pretty damm good too and i think might be easier to obtain as they arent all deleted yet
