I'm commissioning a custom DVD set of Sayonara Zetsubou Sensei. I found the first two series just fine, but I need a working download link (not torrent) of Goku Sayonara Zetsubou Sensei, Zan Sayonara Zetsubou Sensei, and Zan Sayonara Zetsubou Sensei Bangaichi to send to him.

Can anyone give me a MEGA of them? Hard sub is ok as long as it isn't potato quality/watermarked.
