Maybe that's good advice, but I don't think so. It's like advising a struggling artist to go out and paint a masterpiece. I don't have the skill, talent, or time to even do a In the White kit, much less a scratch rifle.
Build one from scratch! Forget the kits. When I started out in the 70's I had my first TC Hawken and drooled for a hand made flintlock. A friend who painted cars for a living showed me his beautiful hand made from scratch Kentucky long rifle. I thought "if he (a painter who is not a trade skilled wood worker) can make a rifle from scratch, so can I". I have made all my guns from scratch, but two. The last one I am working on now has some problems because of factors that were determined/made by others. Pick out your favorite pattern, get a barrel, lock and your parts. There are also lots of parts that can be made with a drill, hacksaw and files.
You will enjoy a scratch build more than a kit, because it will reflect more of you.
