What is better for running, a cross trainer or a manual treadmill? - strength trainer

Hello, I'm 12 a.m. to 6 p.m. times per week. I run and I am seriously considering a piece of gym equipment at home. But I get a treadmill to my overall cardiovascular strength or improve a cross-trainer, because they do not run a lot to do to build, so I can have more muscles. A quick answer would be very grateful.
