All-Clad non-stick works well. I have the All-Clad 4 space waffle maker with non-stick parts - the batter has never stuck and I never had to butter the grittle. I was surprised just how well the thing works and clean up is me wetting a paper towel and going over the grittle when done. And I put chocolate chips ontop of the batter once I pour it in - the 1 or 2 chips left come off very easily.
I also have the All-Clad pancake grittle for the top of the stove that is non-stick. Works great and I've had it for 5 years.
