SWMBO is talking about wanting a replacement toaster ... briefly perusing Amazon for reviews, it occurred to me that one feature that some might find useful on a 2 lever 4 slice machine, is the ability to tell it that you want both sides to finish at the same time, irrespective of what level of toasting is required. I like lightly done toast, SWMBO likes well done toast.
I wonder how it could be done ... some sort of timer chip ?
