I've had my LnL AP for three years now and about the only thing I've found that has been an annoyance is station #1, the shells often do not line up correctly and they hit the outside of the resizing die. I just raise the ram slowly and if it catches I tweak the shell with my finger and all's well.
I must note, however, that the LnL AP did not run smoothly out of the box. The primer shuttle required some adjustment (not major) to ensure smooth operation, and the pawls which rotate the shellholder needed adjustment. These pawls are VERY touchy, I turned the screws only 1/6 of a turn at a time until it ran smooth. That was three years ago and it hasn't required attention since.
