I like EFT quite a bit.
I had been studying qigong and chinese breathing/meditation methods for a while... so I was pretty skeptical about what seemed to be an oversimplified 'half-cocked' approach.
But it works!
It works really well, and you don't have to know jack about the meridians you're working with to have a powerful effect.
EFT is an incredible and simple method that has helped me quite a bit in clearing up mind-body tension, frustrations, limiting beliefs, etc. (I've done quite a few posts on it at my own site).
In addition, Gary Craig gives away more for free than just about anybody.
keep smiling,
