Best approach to buying tools?

I tend to stick with six point stuff, snap on wrenches in particular, sometimes it's the only one that will take that ol' crusty beat up slightly rounded bolt off. For sockets I have S-K, some Matco, Cornwell impacts, Craftsman. Channel Locks and Vice-Grip definitely. Better tools fit the fastener better and you'll take less damage. H-F air tools seem to hold up for my occasional use.
