   TW> GOOD Recall   
      
   YEs, so the cost of the juice might be close to the same.   
   Maybe some difference due to voltage drop on long runs, more resistance, etc.    
   That might be a factor.   
      
   NOw I can buy that the 220v unit, as it's made for   
   industrial strength use instead of home occasional use will   
   have an overall lower cost of ownership over time all other   
   things being considered, but electrical operating costs   
   doesn't seem to be as significant as other factors imho.   
   But then again, maybe I'm missing something important there. TW> Roy can get   
   me easily about Automobiles but Electrical/Electronics   
   TW> in MY field and he is missing something in this discussion.   
      
   Possibly, or something I haven't considered yet.
