Putting together/taking apart Flexy is a huge pain in the ass, and I think mine had 4 or 5 shelves.  The last time I took it apart, I never put it back together and just went the IKEA route (and now I've no real audio toys).  I still have all the rods, nuts, and washers on a shelf in my basement. 
  
Oh and leveling 3 legged ones are a lot easier than leveling 4 legged ones.
