I don't like downloading files. Even when I do download, it's only because the manga issues in question haven't been released in America yet. I also delete them once I finish reading; that way it's like borrowing from a library rather than stealing from a bookstore.

(Yes, it's a convoluted justification. I don't care. It works for me.)

Since Trigun has been released on DVD, I would not feel right downloading it. YMMV, but that's where I stand.
