Splurge on Good Tools - Crimpers, Multi-Tools, Screwdrivers, Knives, Pliers, Wire-Cutters, etc - eBay may have cheap ones, but it shows!
There's an eddy in the time-space continuum where my screwdrivers all migrate. (I believe it's located next to the place where socks go)
So screwdrivers are definitely not a splurge item for me.
I have a bunch of cheaper screwdrivers 'here and there'
, because of what you said - the evil screwdriver-stealing-gremlins!
Unfortunately, they bend, get dull/rounded/blunted very quickly, tear up screw heads, or (OW!) slip out of the slot and stab me, or an unfortunate bystander (table top, mobo, etc.) - They're OK for emergencies or casual use, but I invested in a QUALITY set which I religiously keep in my toolbox for 'Real Work' - the difference is like comparing a Leatherman
to a $6 eBay generic multi-tool!
