Kat, you best hook me up on ICQ..
The best thing you can do is look for an internet provider that has a dialup number in your area. That will cost you only about 0.70 euro per hour at night, double that at daytime.
I do not know freeaccess, but I guess your best bet will be 12move.nl
I have had ADSL for a while now, so I did not really focus on dialup providers
You can also check for hetnet.nl, I am sure they have a dial-up # in your area. They do not charge monthly fees, so you only pay for phonecosts.
