Looking for table saw to repurpose

I am trying to make a welding table on a budget and am interested in finding someone with a broken or not old want Sears Craftsman table saw or other table saw top with a grid pattern that will allow me to clamp down the metal I am welding, so basically it has to have grates, squares or openings big enough for a clamp.
I do not need the saw itself, just the metal top.
but I can take it all if you want.
