Pretty much what Mac just said.

Key questions:
1) What is the ammo end use?
and,
2) What are the accuracy requirements for said end use?
When set up and used properly, a progressive press can be used to load very accurate "match ammo". Look up a fellow named David Tubb...
In my case, I have a LNL progressive which I use to load ammo for NRA/CMP high power (mainly 77's and 80's in 223). I have to load ammo in
volume that is also
accurate for my purposes (MR 600 yard target). The LNL is not without faults, but it serves my purposes in this regard.
However, as noted by other posters, I do not run it in "full progressive" mode...sizing, case prep, priming and related are separate processes. I have also had to do many tweaks and carefully operate said press for best results. They can be fickle beasts.
In my case, when dropping powder with the LNL, ball powder is best choice for smoother operation for volume operations (this is the case for most progressive presses).
As progressive presses go, the LNL is affordable and functional. I feel it is in between a Lee and a Dillon. Regardless, it is a progressive and progressives can be a difficult beasts to master regardless of brand.
