Floor space is very useful and a floor model kills the floor space and the bench space.
I have an RF 30 mill/drill with a big cast iron table under it. With a 2hp motor and 5/8" chuck, it is very capable. It is a round column so it can be turned sideways if ever needed, just like a drill press. So far, moving the head all the way up will clear the parts I have needed to drill. There is a bunch of storage under it for other tools.
So far, I have never had a want/need for a drill press vs. having the mill/drill. It is better than the drill presses I have used and I can do basic milling operations. A lot of times the milling projects are not even high precision work, but just where I need to remove material, and the mill is faster and better than any other options I have. A real milling machine would be great, but that is a different topic.
