I picked up a table on casters a week back. It has a 2" thick aluminum top, but the working area is a bit small 20x38" or thereabouts. I would imagine it would work pretty well considering the tabletop is a giant chill block. Although, I need to figure out a clamping system for it.
I should post a picture, I'll do that tomorrow.
