it depends what u are trying to do and how much you want to spend. do you want a close cut? do you want to be able to change the guard? do you want to spend $35, $50 or $200+?
go down to a sally beauty supply store and ask what they think there.
what r the best 1s 4 a real close cut, i dont even care how much they cost. ive bought like 4 of em in the last year & end up throwin em away after 1 or 2 uses cuz they suck.
JUS BUY SOME WAHLS ONES 4 LIKE 30 BUCKS AND THEN...U UNSCREW THE BLADE....AND TIGHTEN IT BACK UP...WIT IT POINTED 2 THE GROUND... WORKS GOOD WHEN U POINT THEM ON CONCRETE AND TIGHTEN THEM UP...MAKE SURE THE BLADE AND THE OTHER PART ARE STRAIGHT AND TIGHT THEM...THIS MAKES THEM REAL NICE AND SHARP BEEN DOING 4 MANY YEARS....
