Here's something to think about, who has a complete set of self-powered tools as a back-up to power tools?
I bought myself an old style hand-crank drill a while ago to keep in my shop, just in case. Sure, it's not very fast compared to a modern battery powered drill. However, it's more compact, doesn't require electric, and is no where near as complex. If worst comes to worst I can still use it to drill holes just fine.
I also have both crosscut and rip tooth hand saws, keyhole saws, planes, rasps, ect, ect. Sure, I have generators so that I could probably keep all my power tools running, but I wanted to make sure that I could still accomplish all my normal construction and mechanical tasks, no matter what my power situation is.
