I have a complete 3/4" drive socket set(non impact), as well as a 1" drive impact socket set from Harbor Freight. Perfect low cost for my occasional use. Just remembered the 1" air impact is HF also.
As stated, Williams was a good old name.
Somewhere I've seen a special DEEP (like several inches) socket for duals. Gempler's? Shoup? Or you could make one.
