...Two of the main providers have Usenet servers which allow binaries and obviously you need to be a subscriber to that provider to use its usenet server. International bandwidth is way too expensive for downloading large content as you pay per GB, so which forces you to resort to the use of local bandwidth as efficiently as possible...
So Your ISP is charging you by GB if the traffic comes from international usenet-servers?
If not so you could freely choose any usenet provider you wish. In Germany for example i don't know of any ISP who still carries binaries that would be worth your while, thats why over here everybody using binary usenet has a second provider just for usenet wether the providers servers are located in the Netherlands or USA doesn't realy matter...
much liked as only usenet-providers are:
