I assume that you are paying Netzero $14.95/month because it claims to speed up your connection. My sister has that and my brother doesnot, he uses Juno, which is part of Netzero. He pays $9.95. I see no difference in speed and it has been mentioned before on this forum that on a dial-up connection they can only go so fast based on the 56k modem connection. If you keep your system clean, of spyware and virus and do regular disc clean up and defrag, I would go with what ever is cheapest. My sister and brother have been with Netzero and Juno for over five years now without any major problems. Just an FYI.
Good luck,
