Hm, both my former (and the largest) Danish ISP, TDC/TeleDanmark, has binary as well as (faster and more stable) text-only groups, and my current ISP CyberCity does as well. Are ISPs really going so cheap-ass that they don't offer newsfeeds? :O
Otherwise you have the option of one of the commercial feed providers... dunno how much they cost, and I have the impression their main purpose of existance is ware^H^H^H^Hbinary groups.
