If they are priced higher, it is because they are not as common. Meaning less supply. Some people like unfluted cylinders, but it sounds like most who have replied here don't. Which is ok, because it is all personal opinion. Just like I don't understand why anybody would buy a S&W made from mid '90s up. Pure personal preference.

What attracted me to my 629 unfluted was the barrel size of 3", the magna-porting, and the unfluted cylinder. It was a great package for mountain hiking and camping.

When I realized it was a 629-2E, that sealed the deal.

Flutes or no flutes, doesn't bother me. However, I think it is more unique than the standard. Mine wasn't priced at a premium either, and was actually a decent deal.
