That is absolutely ABSURD. I went to snap on website and checked it out, yep $990.
You can get the Tekton 1/4" complete set for $74.
Includes: 5/32-9/16 inch (SAE), 4-14 mm (Metric) 6-point standard and deep sockets, ratchet, extensions, hex bit holder, u-joint, spinner handle, and case.
I'm sure one can get a flexible extension and thumb wheel adapter for less than $900.
