Hi guys, I am researching both presses and I am wondering, why would you purchase a 550b over a LNL. With the LNL you can start with out a case feeder and then upgrade as money allowed. Be able to load both pistol and rifle with a case feeder. Costs less. Auto index. 5 vs 4 die stations. Very easy and not too costly to change calibers. What advantages do you get with the 550b? It seems you could start out with the LNL, upgrade to a case feeder if you ever wanted to for both pistol or rifle, load multiple calibers with out the high conversion cost that comes with the 650 and you get the extra die station if you want to use it. Seems very versatile and you wouldn't ever have to sell your press and upgrade, you just keep upgrading the press you already have. Basically you start with an auto index 5 station 550b and then upgrade to a 650 with case feeder per se. Seems like a good way to go if you want a progressive.
