I picked up a cast iron griddle at a garage sale that was rusty for .50$, it didn't stay rusty for long and fits on my Q's fine. I have cooked steaks on the ribbed side and gotten good grill marks and flipped it over for breakfast doing eggs, hash browns, and pancakes. If you check out Amazon, I believe you can find a new Lodge griddle for half of the Q griddle. I use my griddle right on top of the Q grates and give it a few more minutes to come up to heat. I use mine all the time and it gives me more surface area than the dedicated Q griddle.
