Any opinions on whether the Mangrate is worth the cost? I have a Lodge cast iron reversible griddle that I use for steaks or small stuff or use the smooth side for pancakes and such. I heard about the Mangrate but it looks similar except for the holes in it. If there's something to be gained by the holes I can always drill some in the griddle. Heck, I could get another griddle and still not spend the $$ for a Mangrate.
