Thompson -
I have owned and used the LNL for a little over a year now. Bought it used via the BST forums here. Except for a couple of issues that I recounted in some threads here it's been solid.
I load 9mm, 38/357, 40S&W, 38 Super, and 45 Auto in "full" mode -- that is a case from resizing/decapping to seating/crimping. I really haven't had any priming issues to speak of, but I am aware of the divot/dimple below the primer seater and will be keeping an eye on it.
I use a mixture of RCBS and Lee dies. You do have to watch the length on some of the Lee dies as it doesn't leave a lot of room there.
On 223 and 308 I resize/decap on my RCBS RC, then after swaging, trimming, etc, I complete the process on the LNL.
What calibers will you be loading for?
And I fully agree with Walkalong's statement, if you have problems bring them here, the folks have been a great help in ironing them out.
