If you're in a market where Amazon does 1-day delivery it's close. Otherwise there's Harbor Freight. For the most part though, the quality was good enough that if you were breaking your Craftsman hand tools you were doing something wrong.
That's what heat and impact are for.
Yes, you could spend the money on (air, electric) powered impact tools. You could even spend the money on a hand driven impact driver (much less expensive than the powered option).
Or you could grab a length of pipe and a hammer, slip the pipe over your tools and bang on it. This works better with things that aren't designed to ratchet and uses bits and ends you're more likely to have around the house (or find secondary uses for) than power tools.
Heat is also fire, which means more care needs to be taken.
Which also depends on your budget. They're fantastically expensive but inductive heaters are great for helping break things loose in a safe manner.
That's how I got an o2 sensor out that was completely locked. I spent four hours on it previously. A torch a cheap wrench and a sledge later I had it replaced
They do seem to be assembling their tools in America which is a plus for me.
More recently I purchased a house with a Kenmore Elite range whose only detriment from perfection is that it's an electric rather than gas range.
