Rolleicord IIIs and IVs are great cameras, but since they are far less desired by collectors, they can be had in excellent condition for not much over $100 USD. In my experience, old Rolleiflexes almost always need a CLA, and Rolleicords frequently do not since mechanically they are far simpler. I seen Rolleicords with lens fungus from poor storage, but not many that are not fully functional. A new screen would be nice, but then you will end up spending for the screen and to have the focus adjusted.
