I built everyone of mine out of scrap lumber, (I even used an old door in one section). They look good, are very durable and do the job.
The question in my mind is are you building it to look pretty or are you building it to use. Mine look good but are stained with all manner of grease, oil and paint. I have vices and grinders mounted to mine and they are marked where I have hammered on work pieces and have burn marks from welding. They are covered with drawings and measurements from various projects. To me, that's what a work bench is suppose to look like. But then, that's just me.
+1 OSM my God no! Home Cheapo you can grab a 3/4 sheet pine plywood sand it and seal it...then use a 1/4 of whatever cheap ply you want on top and change it ut when necessary.
IMHO best way to go is ask a pro cabinet shop for leftover strips of whatever his prevalent hardwood of choice is (most in my NY area are Phil Mahogany or Ribbon Mahogany) and glude these up with Titebond III and that is your top. Will have to be a decent size shop but most will give it up because other than what you want to do with it they use it for fire wood.
Last thought, is what I'm doing for a 4ft long bench in my garage for a sink/small work area. Granite guy in the city I work I offered to buy a small leftover piece 4ftx26. He was great, gave me many choices and for $150 out the door cant beat it.
My original plan was SS but way to expensive.
