I build a simple frame of 2X4 screwed together, use 1/2" or preferably 3/4" ply for the top, bolt a vise to one end, screw a power strip to the front, load a bunch of weight on the lower shelf (winter tires/wheels, etc), and call it good. Takes a few hours to build and works fine. If you can bolt it to the floor or the wall, do so. When the top gets nasty, screw another sheet of ply on top.
