VTI audio rack, any good?

I would like to change my audio rack and I need a 6 shelf unit with a high WAF. Price is a major concern and I really can't go more than 500.00. Since I own 2 toploading cd players, I need sufficient space between shelfs. I would need 3 shelfs to have 9 inches between them, the other two could be from 5-7 inches.

Presently I am using a Sanus audio rack but some of my equipment is stacked on top of one another so I want to alleviate that. I have been looking at various racks and found a VTI rack that uses glass shelfs supported by 4 metal tubular columns. Each shelf is claimed to hold up to 200 pounds. It comes with floor spikes. The dimensions are 50" high, 23" wide and 21" deep. My question is, is this a decent rack or should I just keep what I have? Does anyone have any suggestions in my price range? Thanks for your help.
