Does anyone know the difference between the KA 600 and the 620? I have looked on the KA site and compared them.....the 620 is 2 pounds heavier and has a 3-prong plug......both are 575 watt, all metal gears, etc. The 620 is described as a "limited edition" but what is the significance of that? I don't really care about the color which seems to be the $$ difference on Amazon. I am trying to decide which one will be the best for bread dough. Any help will be greatly appreciated.
