I concur. Buy tools when you need them, except for having the obvious,
like pliers, socket wrenches, screwdrivers. I do like the ratcheting
end box wrenches for quick on/off stuff, then do final tightening with
proper sized sockets. A new project is an excuse to buy a new tool...
grin.

Go for top grade stuff. Cheap is cheap, and you will hate yourself.
Sales are good, and beware of "exotic" stuff that you will hardly use.
