Horizontal wet grinder

Does anyone use one of these? http://www.woodcraft.com/family.aspx?FamilyID=4866
I was thinking they might be good for major edge repair. Any thoughts?

I think I saw something like that being used by the DOVO people but noone here does THAT many blades to need that for edge repair. Usually the real heavy hitters just use their belt sanders for really extreme edge repair, but generally if 1000 grit sandpaper won´t fix it quickly, it ain´t worth fixing.
