We also have one like Craig's link goes to. My Mom's cousin gave us her used one in 1981 so we could slice lots of meats (beef roast, boneless pork loin, boneless ham) for an anniversary party we were throwing for my folks. She told us to keep it, so we did.
We've never had problems with it, have used it sporadically since then, and Himself found out that if your counter is slippery you can always put silicone pot holders under the feet to keep it still. Unless you plan on opening a deli I would think it would be sturdy enough for most any house use.
