You can add Ebuyer.com on an almost daily basis through default Poplar, and another site is rapidshare.de (virtually useless to NTL customers)
Its a pain to have to keep changing proxies continually to get some sites to show up, some less technical NTL users must simply think that many sites are often down - not realising that its NTL's fault that they cannot see them

My main beef with them though is that they do NOT give the full 3 meg speed that I'm paying for (at least the default Poplar doesn't..again)
Hersham does (for now at least)
God only knows how completely useless and restricting the proxies will become once 8 or 12 meg becomes the norm...us poor proxied users at NTL will probably barely get above 200k a sec with the current setup..
