For a beard trimmer the Norelco T765 and similar offerings from Norelco work nice. I recharge mine about every 2 months or so and it has a fairly standard 9 height settings.

I wear a fairly tight goatee and use setting 5, so you can obviously go very short to longer with the range it offers. Plus pull the blade guard off and you have a general purpose trimmer for sideburns or your woman's bikini line.
