I realise I'm in danger of taking over Chris' thread hear but a quick reply before I move on.
I do get my full estimated speed 6.2mb during the day and off peak, midnight till 4pm. I schedule ALL my downloads to be done during this time so in theory I shouldn't be shaped outside this time.
Most of my usage wouldn't exceed 150gb say in a month.
Still I will no doubt have another look when my current 12months are up

. Mind you I am also looking at moving back into Sandy or Biggleswade where I will be able to get cable so I guess it's just a case of seeing which happens first.
Cheers
