I like to make my own cords (especially since the AT cables are so long (36") and on my Les Pauls (I prefer the right-angle plugs for my LPs and the straight plugs for my Strats) I only need about 12".  However, at this price, the assembled cord costs less than I could purchase the necessary parts (the Hirose 4-pin connector, alone is $12 + shipping).  I have several of these cables and they all work perfectly.
