Yoga teacher training

Hi!
I am desperately serching for a one month intensive teachers training. There is so much and on the other hand so little information to find. I have found 2 that did sound interesting to me:
One is yogasurfingretreats.com
and the other one is
tribe-yoga.com
Does anybody know one of them? Both of them really seem to be serious and good, but as it is a lot of money I would feel so much better if somebody could tell me about personal experiences with them.

I hope to get some advice.
Love
Andi

Hi Andi,
I did my training at Semperviva and loved it!
Semperviva Yoga College offers two full-time courses this summer, one in Vancouver (in partnership with YogaWorks) and one in Greece, which is absolutely stuning. Check it out:

If you're looking to train in Australia then I don't know the surf-yoga people that you mentioned although it does look like a memorable experience.
The Byron Yoga Centre is very well thought of; also their training is both YTAA and Yoga Alliance accredited. I couldn't figure out if the surf-yoga course was accredited when I checked their website.
