I've considered getting one of those portable induction cooktops to take outside for cooking in really hot weather. And I need to rework the guts of my barbecue grill (we live in an area with lots of mud dauber wasps and I fear there is mud packed into one of the tubes needed to make it run - the last time I used it I barely got heat.) You can still find the old hotplates with the electric coil, or the electric pad, and they're on the cheap end. And you can buy some of these induction units that come close to the cost of the entire stove (four burners on top and a robust oven below).
