I recently moved from using
www.eurofeeds.com , which was costing me about £11 a month for 25gb, to the
www.claranews.com unlimted service for not much more.
I have noticed a considerable difference with retention tho, claranews seems to be only about 3 days, where as Eurofeeds was well over a week for the popular binary groups. But at least i can download as much as i want now. Speed is fine also, get 117k on my 1mbit conny.
