Reply to Massive plugins/presets

So ive been using NI Massive inside Ableton for a couple weeks now, ive created some really cool sounding synths and wobbles, its a great plug.
Ive been looking around for some presets online, mostly dubstep bass & wobbles but i keep running into these sketchy torrent and download sites i dont trust. Does anybody know of a good source for some presets? or would it be worth my time to just buy some, ive found a few sites that look trustworthy to purchase some, thanks for the help guys!
