I have a 4 slice commercial toaster that does perfect toast every time! It can go from frozen bread to perfect golden brown in just over a minute with 4 slices! Its not bread specific either.
The control system is electronic so the 'turny knoby things' (one knob for each pair of slots) do actually change the color in a uniform linear fashion. 1 slice or 100 slices the first and the last look identical.
The only down side is its intended to be 240 volt powered so I had to rewire it for 120 volts and it takes 25 amps now!
3000 watts for a toaster! Now thats cookin!
