I remember having the 44x Yamaha, definitely my favorite CD burner of all time. If Yamaha had made DVD burners, I'd likely have bought one. It burned great with any media I threw at it, never a buffer underrun, and the blue (violet when burning) LED was just plain cool.
44x was where they ended at, and then they got out of the market, saying it wasn't profitable any more. Pity.
