Audio racks that can handle heavy components


I am looking to purchase a reasonably priced audio rack that can handle heavy components. Any ideas or links to audio racks would be appreciated.

Using Quadraspire SVT which limits 175lbs per shelf. Price depends on number of shelves. Very stable with moderately heavy components, including 140lbs amp on top shelf. 

Check out the Salamander racks.  I purchased the single SU20 Salamander Designs Synergy System Core Modules from Crutchfield for $500 each. They support up to 150 pounds.  There are larger versions available depending on your needs.
