Not sure if this will help, since it's a complete minisabre v2 638nm 1W build from a great guy and member gismo. Here is another link to an old sales thread by danefex, who used minisabre hosts for his lasers.
Neither has been active lately, but I think gismo checks his BST thread occasionally.
I haven't found any site still selling the minisabres, but I'll keep looking.
