i use to have a line (several lines in fact)
no headmasters. then i bought headmasters.
no pretenders. then i bought pretenders.
no beast wars. then i bought beast wars.
no non transforming stuff. then i bought non transforming stuff.

now i just dont even bother drawing any lines at all as i know i'll eventually break them.
what can i say, the body is strong, but the will is weak and the choices are vast.
