But just don't run out and buy a Q just because it has stainless innards. There are different grades of stainless..... Units manufactured off shore tend to use 430 stainless which will still rust out within about 3 years. (And then good luck getting parts) The better units from North America mostly use 304 stainless. The best way to tell is to run a magnet over the steel. If it doesn't stick - it's 300 series.
