Savinelli. I see you are looking to buy off ebay so presumably a used (err, I mean "estate") pipe. Sometimes great deals can be found. Not long ago I got a nearly unsmoked Savinelli Punto Oro, with box and sock and with two stems (one acrylic one vulcanite) for 11 bucks. I like my other Savenilli pipes too.
One Peterson I had was a real clunker. I tossed it into the sea in the hope that it will make a better hermit crab home than it did a pipe. Some people love Peterson, even after they buy one with a problem. Among the reported problems are drilling issues , staining problems (inside the bowl sometimes), and whistling noises. You can find lots of discussion about this on here.
