I have the 5 shelf Hi-Fi stand and my mate has both of the stands in your picture.
I'm very happy with mine - the guy is open to a bit of haggling (at the hi-fi shows anyway !). You can change the height of all the shelves by buying different sized columns. Glass is really thick so making it a bit heavy. You can even change the columns for a different colour (my mate seems to be interested in the "anitue gold" effect they do - silver for me though)
i have the av one, its great! if its the av one your after i have 1 shelf spare and would be open to offers - i ordered 4 and whenit came to building the wife decided that 3 looke better and have one spare
