If you compare the specs from the respective user manuals, you'll see that it has the same burr set, diameter, and most of the other elements of the "staycation" M47. The major differences are the beefed-up thumb rest (an improvement, IMHO), the capacity of the catch cup, and its method of securing to the grinder. There'll be additional upkeep because of the last, but not material if it's truly used as intended -- for travel -- and not as a daily driver. The price difference reflects that.
