Yesterday did research on paid newsnet sites and tried Newsdemon. Seven day free trial at $9.99/month for a hole-lota gigabytes. I normally track 11 groups each week on Saturdays and perhaps download 1.5 megabytes, (2 to 3 files) a week. and demon offers blocks of 2 to 200 gb which must be used in a year and can be renewed.
After trying News Rover, their reader, and then NewsBin which I have used before, neither of which worked well, I loaded the server info into my standby, GrabIt. I down loaded my 11 groups and began updating the groups and about half-way through 30 days of headers it froze and gave me a 502 (Over Cap) error code.
For the amount I down load, free (Charter) or (block) is great. Guess I gota keep searchin searchin.
