I've got a several years old Norelco / Phillips rotary model. It's waterproof, which is helpful for cleaning, and the battery holds a charge for several weeks, which is convenient for travel. The shave isn't as close as a razor, but it's consistent and pain-free (I also had rash issues). The trick is that I now *must* shave at least once every two days, or else things get too long for it to work efficiently.
