As oldjim said it depends on your distance from the cabinet and the condition of your line. I am on the 80/20 product and actually get about 51/17. I have read lots of posts in the past where people say they are getting 77 down on Plusnet.
Basically an excellent service, though recently they I think have gained a lot of new customers and their support system has become overloaded. To counter this they are opening a new support centre, which I think will be on stream very shortly. Having said that when I have got through to support (or sometimes posted a message here), they have been very good.
The nature of a forum such as this is almost certainly the posts that are made are bias towards people who have had some thing go wrong, though this would be true of all the ISP forums.
