I'm interested in maybe making a new fab table--similar to the Tab and Slot Design/weldtables.com units. I see they offer as thin as 3/16"....how well do thinner tops work with the wedge-in-place clamps and things? It seems like the thicker the top, the better those would hold...but if, say, 1/4" is adequate it would make my life easier and cheaper. 
Along the same lines, I might just convert my existing welding table by drilling a bunch of holes in it. But, it is not flat, it's more wavy. (it was a used piece of 5/8" steel originally, probably ran over with a forklift or whatever) Any ideas on how I can flatten it out? I checked into having it Blanchard ground, but it's big enough that isn't really an option. (30x97, plus they wanted me to bring in just the top, rather than the whole assembly) The only idea I had was shot down by my wife, although I kinda thought it genius; Flip the table over, and drag it down the street behind my truck. Concrete road would be preferable to asphalt here.
I could also ignore the non-flatness, and just drill holes and deal with it like I have been already, but that's not fun.
