Unless one solely desires to learn the gun building craft, or want a much different style; why would they? When you can buy a kit from Jim that's almost all the way there, of good styling and correct architecture, for a minimal premium compared to a kit from Track or similar... He really did find a niche, didn't he?
For the cost of the kit, and the minimal skill required to get a great result; I'm a bit surprised if in the long run if even sales of completed rifles like Pedersoli's don't take a big dip.
Another thing to consider is that Kibler is a young company. Imagine in 10 to 15 years if they are able to put a few more machines online and expand their offerings to half a dozen or more different styles. This could be very interesting to follow.
