Take a look at this forum click here where you will find people who are looking at almost every satellite available. Look especially at the Linux boxes where you can load 'images' of receiver set ups. You can also connect these receivers to the Internet to keep them up to date.
PC Cards are available but a receiver and positioner will almost certainly be more versatile and easier to set up.
If you go for a motorised dish then you MUST get the pole absolutely vertical (accurate to under 1 degree) otherwise the dish will not scan the satellite belt corectly. However you can get dishes that allow you to have multiple LNB's each focused on a satellite but with a static dish.
