I just gave Skrillex a listen on Youtube. This will more than likely make me sound like an arsehole so sorry in advance but I can't believe stuff like that is considered Dubstep. Not in that it's either good or bad, but it is actually not Dubstep. It lacks the dub of it's Reggae influence and the step of garage influence.
If you want stuff like Skrillex check out Borgore I guess?
Borgore - Cry me a river - YouTube
My recommendation is 'Cheeze Loueeze EP' by Sukh Knight.
Sukh Knight - Hands In Your Pockets Feat Jahcoozi - YouTube
Here's a track from it, it's quite bassy but not to the point where it sounds stupid, imo. It's a quality EP anyway.
Check out the Dubstep Allstars CD's too.
I'm gonna look for my CD and upload it, it's a mix I've had since about '04/05, it has these tracks on it:
