Forster Co-Ax
I added a Forster Co-Ax about 7 years ago. I can highly recommend it because of its ease of use and it just simply produces the most accurate rifle ammo that I have every made. Use it along with Forster’s Competition Bench Rest dies, if accuracy is a is a concern for you.
Keep your Lee press. It will always come in handy for things like Rx dies, bullet pullers, etc.
I started loading in 1987 on a US made RockChucker. Since then, I have owned and used the Lee Classic Cast, Lee Classic Turret, Dillon RL550B, Redding Big Boss II (highly recommended as well), and the Forster Co-Ax. In addition to those machines, I have used a Century arbor press and custom dies when I was competing in Bench Rest Rifle.
The presses that remain on my bench 29 years later are the Forster Co-Ax, the Dillon RL550B, and the Redding Big Boss II. I gave the old RockChucker to my son, and sold everything else. The last time I picked up a boxed RCBS kit that contained a RockChucker press, the box said "made in China and Mexico". I imagine that RCBS makes all presses, dies, etc. overseas now. As far as I know, Forster, Redding, Lee, and Dillon still made in the USA.
I don’t have any experience with Hornady.
