Theres not really any genre specific plug-ins, all depends what your trying to achieve. Do a search for soft synths/samplers etc, been loads of threads about these sort of things, see what other people recommend, try some trial versions etc.
yeah i'm lucky i got Heavy Bassline VSTi 0.8 beta version, i was a tester at their laboratory back in ´92. I've written a non-disclosure agreement signing over my left testicle if I redistribute it however so I can't help you.
On a more serious note, Z3TA is fine, most people use Massive too, then there's Vengeance sample packs that have supposedly the best drum sounds (or so peeps say).
