I know of DJ Strife from New York who's put together some pretty decent sets. She's Brazilian-American I believe and she likes to remix some traditional South American stuff in with some pretty big bangers.
Someone else told me about DJ Mayday from Canada, who doesn't normally mix DNB from what I've heard. They say she loves the kind of liquidy Hospital stuff, so she's obviously after my heart in that regard.
I think you won't find someone at the highest levels of production, though. You're more than likely to find many local DJs making names for themselves, though.
