The co-ax is a pretty good press. It's best feature is the ability to change dies quickly. I took the shell holder off and changed it out for a standard shell holder so I don't have to fight the dysfunctional spring thing. Eventually I will build one that captures the springs so I don't have to fight the things.
It is not as robust as a Rock Chucker. It is just a different design and I don't hold anything against it. It is sort of a modified c-frame press. Reloading good ammunition is more a product of attention to detail and using good dies and components.
The various O-frame presses are all good. So is the Co-Ax it is just expensive and different. All have their devotees.

Joe,
Someone already makes the modified shellholder jaws if you don't want to make them:
