checklists?
 

does anyone have a checklist or know where to find one on NECA's horror/sci-fi figures

spawn.com, has a full list of toys made including their movie maniacs series, as far as neca, no app or list I'm aware of.

I utilize Figure Realm and The Action Figure Archive as a reference point when compiling a lot of the post for my personal site (see my signature line for the address). They're fairly good sites, but a lot of times have incomplete lists. You can also just check my site for some NECA lines you may be looking for. To find them quickly, simply click on the word "NECA" on the bottom right hand side under the list "Posts by Company". I have nine posted so far, and several more on the way.
