Boy Alvin you sure got some good big box stores down around your way. Taint any of them nor any of the autoparts stores nor any of the MacTool and Snap-On tool trucks that I've stopped, that remotly know what I'm talking about, let alone carry them. (How's that Burb comin along??)
I do have the four piece blue handled screwdriver set that ALL the vendors sell. They've worked on everything that I've found on the truck sofar even though they're a little sloppy in the slots.
I also have all of the ones that Grigg mentioned from McMaster Carr and I use them with my Craftsman 1/4" drive 6pt socket set and a 6pt screw driver handle.
