As far as the manual/CNC the only machines I have seen with this capability are Newall, and Prototrak. The Newall machine was excellent because you can create a toolpath with a dxf file. At my previous employer, I even had them cut a spiral in aluminum for a specialized heatsink. It made using the machine extremely simple. I hope to have this type of functionality when I'm done.
Good Luck in your search. If you are looking for a vertical mill that can be dis-assembled and carried down stairs, and is still a versatile machine, try a small knee mill. They can be bought new for about $1500 US, and you could convert it to CNC at some point. I have a small mill like this also,and it's suprizing how much I can fit on it. To move it, it can be broken down into several pieces that are about 200# at the most. I easily moved it myself with nothing more than a 2 wheeled dolly. Grizzly sells several machines like this, and they are also available used on ebay. Here is a link that shows the history of this type of mill, and also here is the link to the Grizzly website, and the mill that I mentioned.
