Here is a pic of mine (Wife is making year end awards for the wrestling team on it currently).
It does 4x duty as an outfield table for the table saw, outfield for the drum sander, storage, and is my main assembly and drafting table. I also used it as a mobile scaffold when I put the lights and wiring on the ceiling.
I used laminate on the top for ease of cleaning glue and finish slops. It does have a torsion top made of two sheets of particle board on a grid of Doug Fir. Having done a fair amount of formica work, laminate seems to work best with particle board of all things. Not sure why, I think there is something about the surface that the adhesive seems to like. And as long as you keep actual water away it doesn't seem to have issues in service with expansion and contraction. I put 3 coats of orange shellac, wax and all, on the underside to seal from vapor and balance out the impermeable laminate.
