I'd check it over very closely, as these big ole monsters did get dropped occasionally, and might have a crack. I will usually go out into the bright sunlight and look all the way around, inside and outside of the side wall. Paying particular attention to around the handle and the area directly a cross from the handle. Then I look over the cooking surface, both sides. Now a older user can have some funky textures caked on it, so remember that cracks will be on both sides, not just on the inside or just on the outside, it will be cracked on both. If I think I see a possible crack, on just one side, I'll scrap that area with the trusty pocket knife and see what is under that crud. 30 dollars is a good price for a 14, IMO.
