I also wonder at what stage you are paying for the Brand Name? I mean, you can buy two hand made pipes made by an independent artisan pipes for the cost of a single Dunhill. Although I do take your point about them keeping their value.
Point taken, definitely. Dunhill has, since its inception, positioned itself as a luxury goods purveyor; to that end, of course their quality control is very high, but--again, in my opinion only--after the first couple hundred bucks you're only paying for the brand name. That being said, the fact that their appeal to collectors is consistent and high, largely owing to the ability to date them rather precisely, is something to consider. If you can justify the expenditure, they're an investment. Regarding other artisan carvers though, there are likewise a broad range of price points there--many leaving Dunhills in the bargain bin by comparison. So it's a matter of aesthetic, in the end.
Regarding ease of cleaning, I've never considered it any different in bent versus straight stems, other than one army-mount Castello that is bent to such a degree that a pipe cleaner simply won't make the turn past the lip. That's never been a problem though.
Regarding my personal aesthetic preference to straights over bents...well, my first pipe, a gift, was a Sasieni straight billiard, which to me will always be the quintessential pipe shape. Perhaps a lot of it boils down to people's personal mental image of a pipe--connecting it with Basil Rathbone's Holmes and a calabash makes that the 'ideal' shape for some, or Magritte's Dunhill LC, or Twain's (or MacArthur's, Frosty's, Santa's, or Mammy Yokum's, or...) corncob, et cetera. Still an interesting question, and a fun topic to ponder over a bowl. :puffpipe:
