I like the Convention at the Capital series because you always get to see a variety of effects from a variety of performers. This means you will definitely find something that you like.

For me it is Docc Hilford's Personal Touch. I love palm reading and Docc's technique makes this good even for magicians who thought that they had no use for such things. Another great item is Florida Keys by greg wilson. This is also on his On the Spot DVDs. Great routine and I carry it set up on my keys all the time.
