I handled one at the local gun store a year or two ago, and was very impressed with the feel of quality. I was tempted, but ultimately couldn't think of a legitimate role for it in my particular case, although if you live on a farm, I'd think they'd be quite useful.
I buy a lot of guns for cool factor alone (despite not being able to think up legitimate roles for them), but those are usually some sort of classic, either real or reproduction.
PS I thought the shallow rifling it them was cool feature, because it's designed to be adequate for stabilizing bullets, but at the same time, it shouldn't disrupt shot patterns as badly as standard handgun rifling.
