I left the Nildram 'ship' back in 2007 for AAISP. I'm very happy. There charging model works fine for me. (I don't do video or music downloads etc) I use daytime and evenings and except for the first part month where I was doing quite a few speed tests, have never gone over my 1 gig quota. (I must be sad!

)
Technical support is 100% plus. As is their technical web page. Usage Graphs plus access to BT fault checking - you can initiate a BT check on your ADSL and see the result. OK, they did have a bad day beginning of January, but their tech support helpline (NOT premium or 0870 rate) had updated messages. I never felt the need to continue after the message. Plus they have a Status page hosted elsewhere, so you can go dial up and access that if you wish and the need arises. As a recent County Councillor, I am fairly busy with email and the County's website. AAISP was my best choice.
