Gas is much cheaper than electric. I have a gas dryer, water heater, wall heater, and oven. My bill is about $25-40 a month in winter and $8 in summer.
I really doubt anything electric can cheaply replicate a roaring gas flame. My only issue with my gas oven is that it is harder to adjust at the very low end to get a slight simmer. I have to hunch down a bit and slowly turn the knob down. Otherwise it is either too high or goes out entirely.
