As you may have already guessed by now, they are indeed reselling Astraweb. Seems to be the exact same service so what one you pick is up to you. Only difference is the BinTube plan is $0.01 cheaper.BinTube is now giving away it's streaming Usenet reader for users of it's new Usenet Access service.
Currently a single unlimited plan is being offered at $10.99/month which includes the following:
Free BinTube Usenet Reader software
260 Days retention building towards 365 Days
US and EU servers
Oh by the way it says you also get free BinTube Usenet Reader software, this is freely available for download on their website but will only connect to BinTube's servers. Well, since they resell astraweb, any astraweb customers can use it too
