"I can't see way anyone would want to add any other tool to their shop".
Denny, I can't speak for others but here's why I like the ultra inexpensive, palm of the hand, old school double flaring.
I like doing stuff that requires me to learn a new skill. It's like learning actual metal straightening rather than slathering on bondo. Once mastered (which takes very little practice) the simple tool does a perfect job, takes up almost no storage space, and costs next to nothing.
Obviously, there are no bragging rights conferred from a tool obtained for $10 on ebay.
