Trangia is the best..for lightweight i would get a Westwind
  and then buy one of those heavy foil windbreaks made for the
  MSR Wisperlight type stoves..the Trangia that comes with its
  own pot support-wind shield and cook kit is a top-of-the line
   gear...the photo was taken for a camping web site i vist..
   at 12 below zero the Trangia boiled two cups of water for 
   tea in 8 minutes..    
 
         I was working so fast in the sub-zero cold that i tossed
     the pot gripper into the pan of hot water..
        first rule of survival--keep your head together!!!!
