I've also heard nothing but good things about Mandala. You should have confidence in knowing that you chose probably one of the top three seedbanks.

The only reason that I personally don't use Mandala is the fact that they are in Spain. I would have felt weird asking for an international money order to Spain and waiting longer because Spain is almost half way around the world. But if you get over those small, miniscule things, Mandala is top notch. He even has grow guides built for his specific strains.
