The pipe arrived today, some minor fills as expected; filled it up with some Pete's Irish Whiskey and enjoyed it very much. This is the first time I've left a stinger in, since it looked like it would take brute force to remove it, and other than having to wipe a bunch of brown goo off it after the bowl was finished, I've got no complaints. The smoke was dry, and the full flavour came through. And unlike some of the newer Petersons, there's no stain residue to deal with.
So, if you see a Dr. Plumb available at a good price, I would say, go for it! The Quintex model is a nice spigot alternative.
