Well my grandpa is the one who owns them for a while yet I hope (at least 40 more years if my great-grandfather's seemingly endless life is a judge heh heh) but I plan to keep them in the family to be sure.
Oh! I just remembered the lads who I used to buy from when I was in the Adobe Wall Dancers (its. . .like Boy-scouts, but aimed at native-american culture. . . well, moreso anyway. Oh and you dance)-- You guys might have a look at Crazy Crow (crazycrow.com) for some of the cheaper stone pipes (and some not-so cheap ones actually) as well as all kinds of cool outdoorsy stuff (knives, and real camping gear not least among their stuff).
Oh, and you can get some stone from them too, dunno how the quality is since I've never ordered any pipe stuff from them -- but I can certainly vouch for the quality of basically everything else they sell, so I figure they're a safe bet for pipe stuff too.

Actually. . I think I'm going to get a few of those cedar pipestems to put in these two dozen or so 1800's clays that had separate stems (but don't have any stem now :P) -- they've also got some great prices on their clays come to think. . .dammit why'd you people make me look up another pipe-seller! I'm broke as it is man! heh heh heh
