I just purchased The Chapters of Marc Spelmann 4 DVD set, and I was wondering, has anyone purchased these dvd's? If you have, do a lot of the effects on the DVD use gaffs? The reason why I am asking is because I am currently in Baghdad, Iraq and I just want to know if I need to purchase anything else to do any of the effects from the videos. I have a pet-peve about buying products and after I get them I realize I need to buy something else to do some of the better or more impressive effects on the videos. Especially since i have to wait so long to get my orders out here.
