if this helps you at all we used to use AOL until recently (we're now on broadband). I have to agree that AOL is mainly pants but the reason we stayed with AOL as a dial-up provider was that ALL the other dial-up ISPs had a time limit to how long you could be online (usually a maximum of 2 hours at a time). The one good thing I can say about AOL having used it for a few years is that the connection is very reliable (much much better than BTOpenworld for e.g) and you can stay online for pretty much as long as you like (we're talking days here if you wish!)
So if you only want to use the internet for little bits & pieces check out some of the other ISPs but if you want to download MP3s, applications etc stick to AOL
