That depends on what you want? Do you want his stuff that is incredibly impractical and lame, or the stuff that is actually practical and enjoyable for the audience.
Front Row Sankey, Paperclipped, Airtight/Airtighter(which is a better more streamlined version that is on his Restaurant dvd) and I'd say that's about it.
Vanishing inc. will release a series of books covering all the stuff Jaynkey has ever published. A 'Complete Sankey'. IMO better value for the money than purchasing hundreds of one trick DVDs.
Here are my top 5 choices for anyone who wanted to invest in some Sankey material.
1.) secret files
2.) The Very best of jay Sankey
3.) front row sankey
4.) revolutionary coin magic
5.) anytime anywhere
