One of the best I used to use was in Al Mann's "The H Factor". You don't post or give the prediction to anyone before the show. Very cheeky, but underated by many mentalists I would think.
Another good presentation is the one in J,G, Thompson's "Between Two Minds" which can be picked up pretty cheaply.
The best versions are in print rather than on the market, but I am not sure the effect is that believable these days. Or may be questionable, for instance, would you have predicted Sept 11th events on that day?
There are several versions in the bound volumes of Magick.
Good luck with it.
