Mill comparisons

[kelseygress]

I am thinking of obtaining a Mill and for space,foot print) sake am looking at the Rong Fu 20" Geared-Head Square Column as sold by Enco. This compared to a full size Bridgeport Mill. What can the the smaller mill do/not do, as compared to the full size mill.
As you can tell my experience is limited, but I mostly work on gun related projects.
Thank you for any information you can give me.
