I have had SlingBox for 6 months. Works great.
Set up was easy. The SlingBox, Cable Box and Router are all next to each other, so no need for any extra SlingLink or such. I did get an extra cable box just for the SlingBox, so no conflict with anybody at home changing my TV channel. I did not hook the extra cable box up to a TV, so no one at home can see what I am watching or even knows when I am watching.
Basic SlingBox, paid $179. I have control of my entire DVR Cable Box.
No complaints and recommend it to everyone.
