Help me choose a new single stage press plz

I'm using an RCBS Rockchucker that my father bought in 1969 and it still works as advertised. Like BigUglyMan said if you plan on shooting longer magnum cartridges in the future a press with a larger opening would be better, and I would go with a cast iron framed press like most are these days.

the shell holder floats and can (technically) center perfectly to the die even if it was drilled off center on the co-ax press. all other variables aside i'm not sure how much of a difference that will make.

I'm familiar with the co-ax. Shell holders on other presses do the same thing. Different methods to skin the same cat.
