I think they are relatively expensive when I checked them out. One of the things I didn't like about the build was they had power strips built in but there is an on/off switch that could easily be hit inadvertently. I asked them if they had a way of covering or removing that on/off switch and they seemed open to customization or putting some type of covering over it. Other than that, there aren't many production companies that have any type of performance table at this level of quality and high dollar presentation for a DJ performer.
What's wrong with a 4x8 deck with different sized legs? If that's too big just rent a smaller deck. If you're worried about lateral stability you can use a pair of decks instead of cross braces if that's easier. This has the additional advantage of providing storage for cases, bags, towels, fans, etc. under the deck. Wheels can also just be moving dollies or similar. No need to make this more complicated!
You can also DIY your own platforms - if the primary use is as a table you can make it less heavy duty: http://soundforums.net/diy-audio/72-diy-mini-stage-riser-platform.html
The Leg-a-matic II makes this a pretty easy build and they are under $10 each.
