I agree completely with Six about smokingpipes.com, I've used them several times and they're top notch!
As for Peterson QC problems, I know some guys are having them, but I've had pretty good luck with them myself. I have 14 Petersons and 3 Savs, all of them are good smokers. Granted, a couple of them have minor fills, but they are minuscule and do not effect the smoking qualities of the pipes.
That being said, one of my three Savs also has fills, more so than any of my Petes as a matter of fact, but it still smokes fine.
By the way, the Aran line from Pete is one of my favorites. I have two from that line, an "03" and an "XL02", both are full bent apples and both are P-lip pipes. They are both among my best smoking bent pipes!
