Don't believe so in alot of places, though I had them when I was in school. That aside, it's not my forte by a long stretch. Woodworking for whatever reason is something I seem to struggle with based on my experience since becoming a homeowner. Learned alot of things, but my carpentry skills still suck.
Not to mention, with the price of lumber, by the time I build something myself and am unhappy with it (which is likely), I'll probably wish I'd just bought one anyway. I'm leaning hard towards this bench from Sam's Club. I like the mobile one linked from Home Depot, but the one from Sam's Clubs seems like it may be a bit more solid.
Just understand that the longer/deeper the bench the more crap that will accumulate on it that you will have to move/find a place for when you want to reload. .
