Several years ago I got 2 stones.
One I got at Sonoma Williams (paid way too much) a big honkin' rectagular stone that was a mac daddy for my gas stove when we were in the big dry ditch. It was great for crisping up a pie.
The other I got at Wally World that was a smaller circular stone and was cheaper but was a total waste of $$ because the gas grill I had at time never got hot enough to use it effectively, which is also one reason I don't like gas grills.
I have a new Kenmore electric stove now and while it heats up pretty fast for an electric, who wants to wait a half hour to 45 minutes to get the stone up to proper temp?
The pizza screen is definitely the way to go for the electric.
Cast iron is always a good choice for pizza as well, 'specially that Chicago sheeit they pawn off as pizza that they call "deep dish".
Nobody uses cast iron here for a Deep Dish........lol
That's meant for dat Jalapeno Corney Bread...
