In my opinion, by the way, you're kidding yourself if you think you're going to be machining steel on that machine. Round rails mounted on aluminum extrusions with a tall wobbly gantry will make it difficult to machine aluminum effectively, let alone steel. Think of projects you can do in wood - for which a wooden top will be fine.
