That is kind of where I land: Peterson has iconic shapes, sure, but Dunhill's take on classic shapes really define them. I have never purchased a new Dunhill, to be sure. I certainly own a lot of estate ones, though. All mine smoke great and I have gotten a couple for $80 or less and smoke them in knockabout situations.
So while I prefer Charatans and a couple others, I certainly do searches for reasonably priced estate Dunnys.
The resale value (usually) on them certainly doesn't hurt either, if you take care of them.
