The BaByliss Carbon Steel Hair Clipper is almost staggeringly good value for how much kit your very small amount of money gets you. As well as the core clipper, which offers 25 cutting lengths and a 60 minute battery life, there's a smaller AA-battery operated precision trimmer that's useful for edging a beard.
