If you really like it, I'd say you should double-dip and get the set anyway.
Typically shouldn't do a blind buy like this at this time, but after seeing the complete series of Kaleido Star used for $12 at FYE, I decided to go and get it. I heard good things about it, and I was actually planning on trying it next, anyway. Getting 26 episodes for under $15, too, was just icing on the cake.
