Don't get me wrong, I wouldn't be without my cordless mini-drill. Its unbranded mains voltage cousin is handy too. Both are very essential, but I discovered that sometimes it's just quicker to reach for the hand drill, put one in the chuck and start working, no hunting for chuck keys or spanners, digging out the charger and having to wait three hours etc.
The solution: Trawl the secondhand / junk / charity / goodwill shops / garage / yard sales / boot fairs for a hand drill, aka an egg-beater drill.
When choosing your drill make sure it is complete, especially the chuck jaws and springs, if anything is missing here - move on, re-manufacturing missing parts is waaaay beyond the scope of this ibble!
Check for cracks in the castings, these things have probably hit the deck a few times in their lives.
If you haven't already done so, try and give it a turn and check to see if the spindle is out of true, again move-on if there's any hint of wobble.
