If it's not made in USA, Germany, Japan, or Switzerland, it does become hard to justify the price. I own a Snap-On 1/4 - 1/2 Dual 80 ratchet set and think they're probably the best ratchets in the world. I also own a SO Techangle that, again, is probably the best in the world.
Other than ratchets, though, I have a hard time justifying the price of a SO open end wrench set vs. a Craftsman high polish open end set... especially the ones with the ratcheting mechanism that has a forward and reverse lever and pivoting/ratcheting closed end. Although, I was just at Sears a few days ago and noticed the price was cheaper... suspicious, I looked at box and found that one set was made in China and the other was made in Taiwan. I was very disappointed to say the least as it appears more and more Danaher Craftsman is moving overseas.
At any rate, if it comes to insulated electrical tools, then I look at Wiha, if it's a micrometer, then it's a Starrett, if its a level, then its a Stabila, if it's pliers, it's Channelock or Knipex, and if it's pneumatic tools, then it's Ingersol Rand.... oh, and if it's something like a breaker bar, then it's Harbor Freight.
Snap-On sells extremely high quality stuff, but I only found the ratchets and torque wrenches (for my purposes) to be one of the few items worth the premium. Other than that, Craftsman Professional, for example, is high quality, usually made in USA, and very easy to warranty. If I'm paying $140 for a 1/2" "lifetime guarantee" S80A, then I don't want a hassle on the warranty... unfortunately, I've heard all too many complaints about Snap On dealers honoring warranties.
