What Should I Buy? Which Is The Best?

Hey guys, I'm looking to buy a program that will let me do more with my Flash Projectors. However, I don't know which one to get. I was looking at Northcode, then I was looking at Multidmedia. I just don't know what to get. Is there a web site that gives a comparison chart or reviews? Have any of you used several and have an opinion on the subject? Is there another thread that addresses this that I missed? Please advise.

Thanks Guys
