I really HATE facial hair (on other people I couldn't care less, but it really bothers me when I have it) so I use one of those disposable razors. I give it a quick shave every other day to keep it looking nice. Sometimes I forget for a weekend or so and have to REALLY shave, and then I get out a new razor.
Edit: I don't like the electric ones for some reason. I have one, but I really prefer the disposable ones
