2) Sears? Junk? Whu? My best tools are Kobalt (Lowes) and Craftsman. Craftsman tools -- especially the dirt-simple hand tools -- are still awesome. And they're still backed by the lifetime warranty. Just two weeks ago, I brought an ancient screwdriver with a stripped and rusty tip to them and I got a new one no problem.

The Sears hardware store in our town is about the best place around for tools, hardware, and half-a-million other things. The thing is the size of a supermarket.
