the best thing about Threefry or Unicorn is that you end clean by ending with the same number of coins that you start out with, so you don't have to build in a way to get rid of extra coins you are palming.
The coins for Unicoin need to be very soft though, to prevent them from "talking" - making noise when they rub against each other. Soft coins help Threefry too, but less so.
So Threefry is my recommendation. Chris does a great job of explaining it. You'll have fun doing it for people or in the mirror.
As far as Homer's stuff goes...if you are new to coin magic it's not really the place to start. But if you have the money to spend, his DVDs are beautifully produced and there is a lot to learn from them.
