Take a look at Atlantis' Reference series product line. Their A/V rack fits your description and is in your price range as well. Their importer's Web site is located at http://www.audioplusservices.com/audiopl/mn1-aps.htm Another link that might be helpful is http://www.hifiheaven.com/furniture-racks.htm Here you'll find links to a variety of manufacturers. Good luck.
Audio/Video Rack
I am looking to replace my current A/V furniture with an A/V rack. My goal is to: 1. better control vibration, 2. Make cable/component changes easier, and 3. not have to move a gigantic piece of furniture this summer. I investigated Townshend products but they are a bit out of my price range. I'd like to stay in the $500 or less range for new or used.
