Wall shelf for VPI Super Scoutmaster?

I'm trying to wall mount my VPI Super Scoutmaster, but due to its dimensions (22x14x6 inches) and weight (roughly 90 lbs) I'm having trouble finding a self that is simultaneously big enough and strong enough.  For a brief moment, I thought that the Solidsteel WS-5 might do the trick, but it's only designed to accommodate tables that are 19.5 inches or smaller.   Does anyone here have experience with wall mounting this table?  
Thanks,
Rob
