I'm using
NewsDemonat the moment. The servers have around a 30 day retention with a 99% completion rate. 8 concurrent connections with a 30Gb per month cap for only US $ 11.49 a month, their 150GB a month account costs only US $ 17.99 and their unlimited account costs just US $ 24.99 a month. The 2 main reasons i chose them were A: Their retention and completion stats
B: they take PayPal, as i don't have credit cards this was a must.
I recently tried
CoreNews but the completion rate was poor and the retention was only 4 days.
