Plain old Schick twin blade disposable for the cheek/neck areas. No creams, lathers, gels, strips, etc. Just hop out of the shower, towel off, and shave. Each one lasts a couple of weeks or so, and I can get a pack of 10 for a few bucks at Sprawl-Mart. I found that the twin blade models with the thin or trim heads were actually harder to get at the right angle, and I don't feel like foostering around at 5:45am!
