I am currently with plusnet who have a usage policy which I love.
Its a usage policy that is 10gb peak time usage (4pm till midnight) and unlimited off peak usage (after midnight till 4pm) so if I ever want to download something I just use my home server which is restricted to start downloading at midnight and finish at 4pm. So I never hit the peak time usage and I can use as much offpeak as I want
. Obviously the pings are not as good as idnet on your CSS server but on any other server I get the normal pings of around 29 - 31ms.
Although I am having a good time at plusnet, My mate is having a nightmare and is changing to idnet in the next few weeks
I dont want to change as I am currently happy with plusnet and would have to pay £67 if I left due to free modem charge (which I sold lol) and activation when I moved house and then obviously the extra £3.50 p/m that idnet charges.
