Is he a creature of habit? I'd suggest getting the newer version of his existing razor if he likes it well enough. Hopefully one that is similar in features and options.
Thanks, PintoBean. His existing one broke and I'm not sure what kind it was. He did specify dry shave. I was looking at Costco, but they don't have a local store. The closest store is Walmart, but Target and Macy's aren't too far away.
Do you know if his previous electric shaver had rotating heads or was a "foil" shaver? If you don't know, I'd come right out and ask him what his preference is (my dad strongly favored rotary shavers).
