My "cube" was mfg. by KD tools, I know it wasn't $10 cheap. You can find them online this cheap, but you still need to pay for shipping. Autozone charges around $20 for the tool I think. Never found one locally for $10. Napa likely has a better selection then A-zone.
My cube came as a matched set with the KD front Heavy duty caliper spreader tool.
I originally got my set for working on my 97 S10, GM brakes are the most fun. All the headaches of 1975 and 2005 all in one truck. I hated that truck...
