If you like Sailor Moon, you've got to read the manga. Its so much more brilliant than the anime.
But now that the Sailor Moon manga is out of print and going to cost a bomb, you might want to just download it.
I'm not sure if its legal but it should be since the Sailor Moon manga isn't in print.
You can download it by using a Bittorent. Get a Bittorent client like Utorent, download the Sailor Moon manga torrent, load it in and download.

It comes with the Sailor V Manga too!
