Socket sets are one thing he will be able to use for the rest of his life. I would say get the best he can afford - I started out with Craftsman (granted, that was some 35+ years ago) and have upgraded from there. Just beware Chinese Craftsman... and remember - you really DO get what you pay for.
Shorty (one of the guys I apprenticed under) used to tell me "Cheap tools give cheap results - do you want to be known as cheap?"...
One of the worst moments on a trip was losing a fan belt on my pickup truck in the Sierras, and not bringing my toolbox with me. There was an auto parts store a couple miles away (lucky me) - I went, got a tiawanic socket set, and hiked back to the truck. Halfway into the job, the ratchet (more like rat s#!t) handle failed. Hike back, get the replacement, hike back to the truck (gee, it's getting late), go to snug up the idler - and the socket breaks. Got back to the store - 10 minutes before closing on a Saturday night - bought 3 sockets, another handle, and a breaker bar, just to make sure I could get it back together. Those cheap tools - cost me more than a snap-on rachet and socket - and the time involved chasing broken tool replacements almost left me stranded for 2 days.
I have nothing against HF - or even Chinese Craftsman - if you understand their limitations. But if it's a lifetime toolset he wants - get tools that will last a lifetime.
