Well I'm going to drop the bomb of information here that no one wants to hear, YOU NEED BOTH!!!, A set of good, most the time expensive tools for the shop/garage to handle the tougher jobs like old rusted bolts and a 6 point snap-on socket, But if I'm tightening up the same size bolt at the end of the dock over water I'm not taking my shop tools, Like others said same goes for truck tools, camp tools, That can be easily stolen. I have tools that I won't take out of this garage and I have my cheap stuff that has never been in my garage.
Gave the ol'lady a decent self contained Craftsman set cause I know she will not need more and she will not lose any and that keeps her out of my tool chest's. If some one asked to borrow something I'd rather lend them a H.F then my Snap-On's. The right tool for the right job is more complicated then most think. Roy.
