Where do you get your Vetiver ?

I know there a lot of Vetiver users out there like myself ,and I was wondering what you use and where you get it.I have a hard time finding this stuff.I use Straight Razor Designs Vetiver shaving soap and it is fantastic ,and I have even made my own soap with Vetiver oil but the cent was not all that great.I also use Vetiver after shave made by Guerlain and I like it but still not that strong as I would like it.Out of all the soaps that I have used I keep coming back to this and would like to try some other Vetiver cented products but not having much luck finding them.
Thanks for your help.

Try Royall, their stuff is uber-strong and quite nice.
