Of course, this depends on how and what you cook. We use our griddle two or three times a week. Pancakes, French toas, grilled sandwhiches, fried rice, sliced ham, to asted buns, etc. DH sometimes uses it for sausage or bacon, but I prefer to use a fry pan for those due to the grease / cleanup issues.

Before we bought the cooktop we had an portable electric griddle we used a lot so we knew we would use it.

HTH

With that being said, finding one griddle that is 22-24" long is just about impossible, I might end up with 2 11" griddles that way I'm not storing some giant thing in the cupboard, the smaller ones will fit nicely. Also, if I don't need the larger surface, I can just use one smaller griddle.

I guess you just have to decide on how you cook.

Good luck with your decision.

That said, I also will point out that the contiguous burners allow you to slide pans around very easily, so if you get a griddle, think about getting it with 4 burners together and the griddle to one side instead of in the middle.

I'm definitely in the school of thought that a wonderfully-seasoned cast-iron griddle is the way to go, at least until you hit 48" or bigger.

19" x 8 1/2" cooking surface -- as one option -- Looks like well under $50 ($44 at Amazon today).

We only make crepes. We have crepes every weekend. Can't do these on a griddle. We make American pancakes (that's what we call them) about twice a year. My kids don't lke them nearly as much as crepes. I grill sandwiches on a cast iron pan, not even once a month. So for us, the grill would NOT get used very often.

How do you cook? This is the most important question.

This griddle stays within a fairly tight temp range and is very even across the entire surface. Cleanup is a simple scrape with the spatula and then a wipe down with peanut oil after it's cooled down to warm. It came with a cover both because it will discolor and it's important to keep the surface free from scratches and stuff for the next use.

Oh, I just googled it, WOW, they are still for sale, but boy are they expensive now, didn't pay nearly this much for ours--guess that was back in the test market stages. You can also get a smaller one!
