I read that article several years ago. I wish I hadn't because it helped reinforce my choice of buying a LNL AP. I returned my LNL. To be completely fair had I not owned the 550 for several years first I would have spent more time trying to work out the issues I was having with the LNL. If you don't want a case feeder and your not spending 90%of your time loading 9mm then it is still a viable choice.
I would describe the differences as the LNL AP being home owner quality were as the Dillon is commercial quality.
If you are going to buy a case feeder the price is so close you might as well opt for the commercial quality one any way. I am going to agree with Brian Enos and say that the vast majority of reloaders should just buy the Dillon 550 and done with it.
