I've been planning on getting a Redding 7 turret press. It seems to get high marks from just about everyone that uses it. It would be nice to not have to screw in and out my dies to switch between my Grendel and CM.
I have owned a 1st generation Lyman T-Mag and loaded on a Lee turret and 2nd Gen T-Mag. The Redding T-7 is a much nicer unit and it is what I replaced my T-Mag with. While I now mostly load on my Dillons, the T-7 still gets a bit of bench time.
