1988 - present figurine variations info?
 

I know this thread has probably been created 100 times over , I couldn't find it in search so if someone could kindly send me the link that would be great.

Otherwise,
I'm starting to tick figured off my checklist from 1988 figures to 2012. I understand completely with 1988 and soft heads etc, variations between April with blue strip and non strip. But what others should I look out for ? I understand The ace duck with hat or without? And what variations are more harder to find ???
Thanks in advance !

So did some research and came.up with the following , feel free to correct me ,
1988 turtles hard head / soft head / fan club
1988 shredder, splinter, bebop and rocksteady hard head / soft head
1988 April with blue strip / without stripe / orange belt ??

1989 Ace Duck with hat on / without hat on

1990 Slash with black belt / purple belt and yellow S / purple belt with Red S

1994 Shogun Shoate purple accessories / orange accessories ????

Please help correcting this list
