Solid point here. The one "stocking stuffer" you may want to get him is the 10mm socket set from harbor freight that has all sorts of 10mm bits and pieces that get into/out of all manner of sticky situations.One more thought.
How important do you think a starter kit needs the SAE. Most of what is out there has both. Most of what I/we work on is metric.
I personally would rather have a few more 10mm pieces than SAE.
