I use the industrial "pallet racking" available from Home Depot. I think that they cost me around $50-60 per set (4 shelves), but they have a claimed capacity of 1500lbs/shelf. The shelf material is MDF (medium-density fiberboard), and is very strong. I feel very secure that these shelves would be standing long after I'm gone.
