You can be attuned without cost actually.
There's a growing movement of free healers.

Here's a link (though don't put your email address in it, unless you want to be attuned within 24-48 hours) for being attuned for free to Usui Reiki:
www.reikisecrets.com

It's legitimate, and they give you the option of ordering a book for additional learning, but it's not required.
A girl I know, just recieved her attunement, and she is still whirling from the energy, but she is happy.
