First off, welcome aboard!
Now to the pipes in question. It's true, Peterson has been catching a lot of hell here recently for quality issues. In my opinion, some of these "issues" seem questionable, while a few do seem legitimate. Myself, I have 17 Petersons in my collection, none have issues and all of them are great smokers.
I have many different shapes, sizes, P-lips and standard ft stems, straights, 1/8 bents, 1/2 bents, 3/4 bents and full bents. I have pipes from many of their different model lines, including 2 from the Aran line and 3 from the System Standard line you mentioned.
I'm sure there are a few floating around out there that do have QC issues, but I've been buying Petes for six years now, both new and estates and both in person and online, and I would not hesitate to buy another!
That being said, don't rule out pipes by Nording, Savinelli, Butz-Chouquin, Stanwell as well as Nording's Eriksen brand. I have pipes by all of these makers as well, all of which are great smokers!
