Corey,
I would like to start by stating that I do not have Shinanigens, but I have done my research on it. My answer to you is that it depends on what you have and can do in card magic. This DVD is mainly a collection of color changes and card productions, which is cool, but there are other things that take precedence. Do you have all of Card College? If not, than keep getting those. Do you have Royal Road, Expert Card Technique, and Expert at the Card Table? The lack of these key staples will show in your magic a lot more than the lack of a couple of color changes (I know because I can pull of some great routines while I stick to my two color changes that I have worked on over the years). I don't want to play this DVD as a bad buy, I just want to emphasize that it isn't the best first buy. If you do have these, and are regularly working on them, then by all means, go for it.
