All my barinas are still working (garage and basement workbench).
For build your own workbench, I glue and screw two layers of 3/4" mdf, drop in to a 1.625"x.5" dado on a 2x4 frame and drop a piece of masonite on top as a sacrificial layer. Not expensive, strong as *&^*^ (as long as you don't get it too wet) and a nice dead surface.
