Totally agree: 1-50 is like Ultimate Turtles in the sense it takes all that has come before and mixes it into a satisfying revigoration that still feels fresh. I read a few issues after 50 and felt lost because I missed some of the miniseries.
I've been dabling around with making custom boxes for some of my figures, and I've been using poster board to built inserts to hold the figure. I'd really like to try and make plastic inserts instead, but I'm not sure how. Does anyone know of some resources online that could help me out?
