I had the old Tmag for a long time and it worked well and was convenient to use. The new Tmag II is supposed to be better than the old one. You may want to compare it with the RCBS Turrett unit and its kit if available. I am looking at the Redding Turrett press to replace my rockchucker. As far as components of RCBS and Lyman they are pretty close so don' t let that faze you. If you want to jump up in quality dies,scales,measures etc buy Redding.
