Well i gave active-news a shot - but it definitely seems you get what you pay for.
Using Newsbin Pro (Great prog! Thanks to all those who recommeneded it!) most of the stuff is pulled from my free ISP anyway - and there seemed to be quite a few error messages from the active-news servers. Not that quick either. Also the 1gb download limit is actually split between 3 servers - 300mb a day max on each. So i don't really recommend it. Paid for 1 month and that's it - have cancelled already.
Have just signed up for easynews - their trial 3 days worked great, and seeing as my ISP news serevr (Pipex) is nice and quick and carries a fair bit the 6gb/month should be plenty for just grabbing the few missing posts.
There you go - my news server feedback!
