right now i'm using
people pc online
it's 10 bucks a month (with one month free), don't need to use their software (you can call them up for signup and have them create an account for you, then tell them you want to use dialup networking instead of their software). quite fast (50k most of the time), and have been quite reliable so far (i just dumped aohell about a month ago) -- got around 200pings for UT, which is quite good considering 300+ with aohell
one thing happened to me when i dumped aohell, i couldn't use other isps. so i had to reformat my whole compie and finally this dialup works. after that it's been a good exp so far.
if you're looking for others, you can check out
isp directory at freedomlist and see what you can find there.
also if you don't know how to setup dialup networking (i assume you know), you can call their tech support (i mean ppc techies) and ask them to step you through (they're open 24 hours)
and btw, whatever the csr said when you're dumping aohell, just tell them to disconnect your acct right away. otherwise they will "keep your account active in case you want to come back" and may charge you again if you don't call them up to confirm disconnecting your acct.
have fun
