I've got a Dillon RL550B and I wouldn't get rid of it for anything! I've had it for 15 years now and it hasn't skipped a beat or had any failures yet.
I did have a problem with a resizing/depriming die once,.. I called them up and I had a replacement in my hands 4 days later for FREE!
They live up to their "NO-BS" Warrenty!! :toast:
If you or anyone else plans on reloading a Dillon Press is the way to go!
