Thanks for the info guys.
You have all given me information to think about.
I am an "old-time" Champions player who has decided to (finally) update with the 5th edition stuff. I have alot of the 4th (and earlier) edition stuff, and updating my HERO Library is proving to be expensive.
Although I have 4th Edition Ninja Hero and UMA, I will more than likely update those editions as well -- in time.
Again, thanks.
