Beginner Tip

I started to take an interest in Usenet a few weeks ago, however I would welcome advice from more experienced people. I currently have eweka as a provider, sabn, the ar* suite (I'm currently trying Hydra2 instead of prowlar) and I use su, finder, geek, scenes (paid subscription) and alt for free. I haven't been able to register on DS yet, it seems very good based on the reviews (but complicated to register).

My question is there any point in having several suppliers with eweka or is it useless?
