I wouldn't change my advice even for a normalfag. When I demoe'd my rig to people before the quest came out and they asked for what was the least expensive buy in I always went with a cheap wmr + minum viable rig. However, now I think the quest is the go to for everyone but those with a vr capable pc already. 
Tell him he should go for a quest or if he doesn't want to spend that money then pick up some chinkshit phone viewer from a dept store but understand it's nothing like a real headset. There are really no better options, anything else will ruin his experience and every-time that happens it sets VR as a whole back.
