cd storage

Looking for suggestions for storing cds. Currently use the horizontal standalone units but these tend to be a less than optimal solution - basically you have to slide out each cd or flip through at an inconvenient angle to see what it is. Does anyone have a different method of storage or any helpful suggestions? I would like to find a drawer unit (kind of like the old card catalogs that libraries had but with larger area drawers -or something similar. It should have a high capacity as possible - need to store somewhere between 1500 and 2000 so the fewer units the better.
