At the moment we have chorus and shock horror ......... I don't actually have anything bad to say about them. Its chorus digital and to be fair have neaver had to contact them since we got it (almost a year) so I don't know if alot of the complaints relate to the analogue service - r if we've just been lucky!
We stopped get a bill after a couple of months but I have been told that you need to let them know if you want the invoice every month (on the DD option)
The only extra channel over sky is c4, and I think the package with sky is better, unless your a BB fan almost everything thats on c4 appears on e4 at some stage. With all the channels tend to just flick around a lot and end up watching rte/bbc
What we are thinking of doing is getting sky for a year, pay the subscription for the year at which stage we'll own the equipment and then cancelling the subscription and just taking what ever channels come with it. Once the sky subscription is gone will have to put up arial to get 4 irish channels. (think €120 -€150)
I have seen ads for installation without a phone line - think they charge installation charge though, rock/hard place - if you want it without the phone line pay a bit extra
