don't let anyone tell you the smoothness of "old" pans just got that way from years of use. I am a daily user of cast iron and collector and have quite a collection (>140 pieces) and bought my first pan of my own at the drugstore when I went out on my own 28 years ago. It was very smooth when brand new. Whatever this technique is that they are selling today is something else entirely, and I am sad that so many people today are buying this "pebblestone" finish and trying to convince themselves (and others) it is all just so great. It is not that hard to find a good piece of the old, smooth stuff out there to buy, and read online how to clean off the rust or excess grease caked on, and you will be starting with a piece of iron like when it was brand new years ago. Then get busy seasoning it a little bit, and start using it. When buying a used piece, just be sure to tap it lightly with something hard, like a ring or key while holding it suspended, loosely, and be sure you get a nice "ring" to the sound, not a "clunk" sound, to avoid buying a (hidden) cracked piece by mistake. Good Luck!
