Does digital Dubstep really exist? I've only ever seen stuff like Burial and Benga on CD and there are a few things for download on Juno for example but the majority of stuff seems to exist on Vinyl.

I'm moving abroad next year and getting Dubstep out there is difficult.

there's a Sticky thread just above this one you posted called "Newcomer's Guide":

there are links to lots of useful threads, including one which contains a comprehensive list of vinyl/digital dubstep retailers.
