Help recommending a hack

I'm just looking for a client or script that has auto-nexus, aim, and auto-loot; anything else is a bonus. If you could recommend one—and maybe explain how to install it—that would be great.
Or do you recommend using the Realstock one?
Thanks, Realmers.

If you want something simple that just works, just use RealmStock. If you want more advanced hacks check out RealmEngine. RealmEngine is rough around the edges still but has a moderately active community with a few people working on making it better.
