Goodluck.
I have never needed more than binsearch.info to find anything on usenet.
Thanks. I've used it too, but a lot of files I got from binsearch.info were passworded, requiring you to fill out a survey or something to get the password. I've had similar issues with NZBClub. Also, a lot of their NZBs were unable to fully download using astraweb alone. The utter lack of convenience caused by either issue was enough to stop me from using no-signup sites like binsearch.info.
