Best 4 or 5 shelf rack for electronics

I would recommend Sanus racks. They make 4, 5 and 6 shelf racks. They are really good.

Also, there's this British company that makes great racks. There racks look so gorgeous. Here's a pic of them.

I think you can pick up a 4-shelf Mapleshade Samson within your budget: http://www.mapleshaderecords.com/tweaks/samson.php

I'm very happy with the quality of my Billy Bags rack. They are available in many custom finishes, and are built like tanks. Cheers,
Spencer
