Hmm. A bit of advice if you REALLY don't want to spend that 30 dollars- since you've been in card magic for about 2 years, you should have enough knowledge to register for Marko's Learned Pig Project.

If you considers you enough of a "magician," he'll grant you access to quite a bit of public domain material. He has Annemanns Practical Mental Effects in Ebook form, which is recommended as one of the great starting points in mentalism.
I don't reccommend this however, and go along with the previous advice. Another book I would recommend is Practical Mental Magic/Effects (mentioned above) which is a great resource and only costs around 7 dollars.
