probably effects new pipe sales less then cheapo brand new pipes do. Basket pipes as they're sometimes called turn more dollars away from more expensive pipes I am sure. Oh wait do not forget about those other materials, those corn cob pipes I mean if word gets out how good they can be that's gotta cut into the sales of briars negatively. Honestly though I think it's one of those things where it's not really measurable. How many new pipes have been sold because someone got into pipe smoking because a nice estate pipe made dipping their toe into the water not so expensive for something they might not stick with. And then the PAD sets in. Or how many people were going to buy a pipe new or estate but went estate? I honestly think the long term over all effect of estate pipes is probably more of a net gain to pipe makers then a drain. That said I've never bought an estate pipe and the temptation only sets in when I see a pipe that I've fallen in love with and that is not available new, and then someone else snaps it up before I can figure out how to make space for it on the pipe shelf.
