How reliable has your press been?
Did you have the famous primer issues?
Mainly because of this I'm looking for a new progressive press, and Lee is not on the list.
I once bought a Lee Anniversary kit with the Challenger press and it still goes well. One thing to watch though: never let the bolts in the toggle get just a bit loose, this can lead to cracking of the toggle's material which is cast aluminum.
Later, I inherited a Rockchucker press and the Challenger was then promoted to primer seating with an RCBS automatic strip primer toolhead on it; it works like a charm.
I really like the new Lee cast iron Classic series. Had I not got the Rockchucker already, I would have bought one. Maybe I'll get a Classic Turret, it looks like a good one for multitasking some jobs (I have many odd calibers to load).
As for the infamous Lee Tray primer attachment, I keep it clean and spray Jig-A-Loo in it periodically and it still goes well on my Lee PRO 1000.
Just don't bend it, it is very sensitive to ANY mistreatment.
On the PRO 1000, I deepened very slightly the three grooves on the rear post to increase the amount of tray shaking. It alleviates the problem of primers hanging up. I also do not wait for the primer tray to become empty. As soon as primer level reaches the top end of the through, I fill it.
I have been thinking about making a small hole in the primer tray to fit a blocking pin. This would help loading and unloading the tray.
