Anyone have experience with various brands? High-BTU burners with a nice, low simmer? Preferably, all the burners go to the max AND simmer. I don't like it when the burners are all different sizes. Open burners or sealed? Also, I think I want duel fuel; gas ovens have given me headaches in the past. Also, all burners? Or would you get a griddle, too? There is no way I am doing an indoor grill, but I might consider a griddle. Some say that the griddle, if used as a simmer plate, is very effective. Since I make a lot of sauces, this is pretty important to me. I just started looking into this, and the array of choices is bewildering. I have little doubt that many here will know a lot, and also have strong opinions, so have at it. Thanks.
