Now you just need a compressor, grinder, welder, sawzall, clamps, magnets, drill, drillbits..............

Thats true overdrive, but if you already own every hand tool you never find yourself in a situation of needing to go out and get a new one. Convenience my friend.

I can't help but think that 80% of those tools will go unused unless this ends up in a professional shop where you're seeing 20 different makes and models every day. My preference is an empty box that I fill up with what I need as I go. A hell of a lot cheaper than $12k too...

It depends what you're working on. If you are a hobbyist and your car is more than a few years old, chances are you'll only need a handful of sockets, wrenches, pliers, and screwdrivers.
