Depends on whether you want SD or HD. With a little practice, you can easily set up either a small 18" SD only dish or a larger slimline 3 HD dish attached to a tripod or similar support structure.
You level the dish support (very important for HD) and then point dish towards the SE sky, using a separate sat meter or your receiver to adjust it to the strongest signal. I can do this in less than 5 minutes, assuming there is clear view to the sky.
Whole set up costs less than $100.
