What are your opinions on these...

Scientology and Eckankar? I seriously want your opinions. I grew up in the traditional christian home and going to church every single Sunday but I went away from that and started to dabble into other religions. Right now, I'm not apart of any religion but I had taken some interest in the two mentioned earlier. But I seem to notice that some people I come across in Scientology act a little "whacked" out after they get involved with this religion. I don't know if it's the "auditing" that has made serious changes in personality but I would like more info. and opinions.
