What is so extraordinary about Luciano Pipes is that they devised a way to provide a very high quality Italian pipe at a kind-of "artificially" low price. They are "Hand-Finished" Italian pipes. This means that part of the process is machine-assisted, but the most important parts, like drilling the holes, are done by hand.
This allows for some economies allowing the pipes to be high quality, but sell for much less than others of the same quality. Actually, several of the Luciano samples I saw were better quality than a 100% hand-made Italian pipe that I have, which shall remain nameless.
