I too would vote for The Gunsmith of Grenville County.
And yes, I get the sticker shock many experience when they see it listed in the 35-50 buck range depending on the vendor.
But consider that, at the high end, say 50 bucks, plus the cost of a pattern 10-20 more bucks against the 800-1000 dollars worth of parts and a couple hundred hours of your time to build the rifle.
70 bucks would represent no more than 7% of the cost of parts and that would drop to 2% if you figure your time is worth $10/hours (ya we work for free when working for ourselves, but it still has some value).
And if a good book saves even one mistake, then it's probably worth the cost.
