We don't have cable and use Wimax Online for the broadband - this works via a dish pointing at a ground-based antenna. This costs us €30.25 per month.
We use Rainbow Satellites for the TV and pay €30 per month for just about every channel under the sun!
In general, it's very reliable, apart from if there's a storm, etc. which you can understand must affect the signal. If we have a problem, we also turn the wi-fi off on our mobile phones and other devices (which seems to help a little).
