I'm with PlusNet and while i would agree that they are great when you don't have any problems, be warned, they suck when you do. I have been fortunate in that i have only ever had problems twice but both times i ended up telling them what their problem was. I have been with them for my entire time on ADSL btw - 2 years. Was on NTL cable before that and i have to say that was terrible in comparison!!! They even billed me for months after i left - or rather they tried, obviously i cancelled the payments as soon as i got wind of it

Their (PN's) solution was ALWAYS to switch the router off for an hour and switch it back on again. Kinda awkward when a) you know it won't help the problem and

Also, the 30:1 contention is only on their portion of the network. You will still be provisioned on a 50:1 line at the exchange. What impact this will have will depend on the capacity at your particular exchange - there is an exchange checker at http://usertools.plus.net/exchanges/ (poss. members only but i don't think so).
Don't get me wrong - i think i would still recommend them, but you should be aware of these points. It's not all roses!!
Their user forums are here: http://portal.plus.n...orums/index.php
You should be able to login using the user and password both as "guest". Take a look for yourself. There is a LOT of unrest amoungst their customers right now.
Judge for yourself.
