Haven't moved up to a progressive yet, still single staging it (have 2 Lees).
Most of my equipment is Lee, some RCBS dies, a Lyman 1200 Tumbler, various odds and ends and tools.
Saving up for a progressive, so far keeping my eye on a Dillon.
Can't praise enough the Lee Universal Decapper, I have really worked this thing to death and it keeps on going, Lee makes one of the strongest Decapping Pins in my opinion. Real tough workhorse especially on those tough military primer crimps.
I think I will always use the singles for small jobs even when I upgrade, plan on making one a dedicated decapping station.
Agent Ronin, thanks for the tip on the Uniquetek scale, I am looking to also upgrade to a nice scale and that one looks pretty good.
So far I have no complaints or problems with any of my equipment (other than self inflicted screw ups!) I do like the RCBS case prep tools that have the threaded screwdriver type handle.
