Direct downloads are hard to come by, though by accident I found like 35 volumes of raws. HQ even. But that was not on purpose, and I cant read Japanese so other than lookin' at the pretty pictures Oda draws they are of no use to me.
Anyways, I don't think they are out there at the moment. I use ISOhunt or demonoid to download ish. BT works pretty good depending on what kind of connection you have. I've downloaded eps 30-205 ( 40 gigs ) in the span of a few weekends. Usually 30 eps at a time.
