Product review (1 stars): Stay far away from the electric model!
I can't comment on the dual fuel aspect; all i can say is i hate our electric model.  It takes 20minutes for a moderate size pot of water to boil.  Ridiculous.  The burners constantly cycle, it's horrible.
My wife fell in love with the olde style look (not this one) and she totally regrets it.  I regret it not only for the poor function but the 2x price and the custom install i had to perform - now i'm stuck with this odd width.
I hope i help someone think twice about their purchase.
