I use Earthlink. I like them, except for tech support. (95% Indians who don't know what you are talking about.)
My brother uses Juno. I don't like it, he does. Juno is more limiting on their 'unlimited' hours -- kicking you offline more often and suspending your account if you use too many hours. Plus they make you install their special dialing utility which forces downloads of advertisement taking up bandwidth and potentially lagging you at the wrong time.
Most dial-up services you get are going to be resold accounts anyway, using the same exact connections/numbers/equipment as their competitors. So most likely whoever you go with, its a good chance its going to be the same exact service, just like resold DSL.
