I just got my 19 y/o off the electric razor (actually, it was at his request), but only using the multiblades so far. He's away at college. I'll move him into the DE when he comes home for summer. I don't think straights would be practical living in a dorm.

Also, I am evangelical about DE shaving when talking to multiblade shavers. You can sell the extreme cost savings and the bbs shaves. I love my straights, but they are not economical compared to a DE, and of course they are a pain in the ass to learn and maintain. I get help, which I am happy to get, but that's not a selling point for someone looking at options.
