It's really good. I've seen scans of it for ages, but I thought that it's just pointless smut, so I was really surprised when I read the scanlation and realized that it actually has a good story. I cried all through vol 3. ^_^' The first volume of Hoshi no Yakata is also the most expensive manga I own... I paid about $43 for it used. Most of the volumes in the series are lots cheaper, though.
Anyway, in case the links on the page don't work, they might have them in the yahoo group. If not and you're interested, let me know and I'll upload the whole series on Megaupload for you.
