I have been using my new MEC Marksman hard for about a month now. No issues. Just realize there is no priming on the press. You will have to either get a ram prime or prime some other way.
It is silky smooth, makes straight ammo and it feels right. Get the mount with it. The mount is low enough to feel comfortable sitting but tall enough to use standing (for me anyway, I'm 5'10).
I am selling 3 of my O presses to make some room. I'm still keeping my Forster Co-ax for now, but that might be the next thing sold on ebay.
