Firstly, are they really terribly awfully painful? I am used to waxing (although fed up with the faff of it). And I wouldn't be using it anywhere except my legs.
Secondly, can you recommend any particular type?
Well, I got a bit carried away, and popped out to Argos to buy a Braun Silk-epil xelle (had £15 off). Have tried it out, and am quite pleased. It's not horribly painful at all - no worse than waxing, although it took longer. Hurrah. Quite impressed so far anyway. Cheers for all your input.
