I've tried Blue Light (aka K Mart) and Netzero back when they were "free". I recall the very first Netzero ad window. Half the time it didn't work, so I had no ads, but "they" got better. I use to alternate between Bluelight and Netszero to get by their limts (didn't want to pay). The ads didn't bother me, but as soon as they started limiting to an unrealistic number (like 10 hours free a month), I said, no thanks and switched.
I still pay $8.99 a month for my dial up now. The best I can get is 50.6, but I'm out in the "stix". I'm not with Netzero or Bluelight. I'm using Highstream [url]www.highstream.net[/url]. I don't mind them. The only stipulations (that I've noticed from reading) is that if you get disconnected, you have to wait 1 min before reconnecting. Also, your max allowed connect time is 5 hours. So, you can be online for 5 hours, disconnect for 1 min and start another 5 hours to my understanding. Haven't gone to 5 hours straight yet to see what would happen...
I haven't had any problems with them. Few times I get 26.6, but usually disconnecting and relogging gets me to 48.9 or 50.6K. They have this dialing program that you use (I assume that Netzero and Bluelight still does), but I managed to use a direct method... as in just program a dial up via inside Windows (manual I assume) and not use the dialer. It works....
