I have a Hobart N-50 that I bought in a thrift store for eight dollars (bare machine) and it cost another $200 to set it up...2 bowls, whisk, flat beater and dough hook. I found a copper bowl liner for it on Craigslist, someone gave me a grain mill attachment, meat grinder-sausage stuffer came from eBay (all metal), another plastic-bodied from a thrift store along with a roto slicer/shredder attachment. I also have a KA 5-speed hand mixer and a Braun 200 watt immersion blender. They all have a place in my kitchen, and they all get used. I will probably wear out and replace everything but the N-50. If you want a KA stand mixer, check Craigslist in your area. People get them as gifts and put them in the garage until they need the space or the money, then sell them...cheap. Like this, as a starter
