Well, You can go on #dalnet on IRC, there is a channel called #Mangaproductions, or the sort, they actually translated both trigun mangas
They got some others there as well, as well as a site to d/l them from, I am sorry I dont have the site handy, but if you search around IRC or know someone who uses it, all I can say is good luck, and at least for the Trigun, they start off where in the series Vash is in a twon eating pancakes and the whole town is after him for the bounty, hope it helps
