Nothing wrong with supporting SK if they're the quality level you want and need. Early on, I upgraded a lot of my miscellaneous tools and Craftsman to SK. They were good tools then (1980's) and even better now for many of them. I have upgraded most of them now to Proto and Snap-on, but have bought one newer metric full polish wrench set by SK that I really like.
I was just pointing out that there may be other things than the number of items in the set that you evaluate for, on some of the most demanding tools. I've had lots of swivels over the years, including SK. None have been as good as the Snap-on I have now. Based on that, I'd buy snap on over SK even if I got 30% more for the same price in SK. Others may go with the 30% more. You pays your money and makes your choices, and sometimes it's awfully hard to tell, even in retrospect which choice is better.
