I think it's entirely up to you. If you have any concerns, why not just get a new one for thirty bucks or so. Since you mentioned the angle grinder I will share my experience. I picked up a reversible(grill on one side, griddle on the other) cast iron griddle from the "Pioneer Woman" collection. It fits across the back two burners perfectly with the handles...and recalling, it wasn't too expensive. Bad news is that no amount of seasoning or use allowed anything like a non stick and I mean I would massacre a fried egg bad! Now the angle grinder angle(?!!)...I took my 4-1/2" peanut grinder, put a flap wheel on it and took the surface down to smooth, re-seasoned it and it works amazing now. Of course when I search the net for the one I have now, I can't find it! What are the dimensions of your? Pic maybe?
