I'm sure this question has been asked many times on the boards, but I wasn't able to find anything.

Where can I find an up to date price guide online for the Kenner vintage figures? I have two ESB Yoda's MOC that I would like to price. The first is a 47 back Yoda with brown snake with the 4-Lom offer and the other is a 32 back Yoda with orange snake. Both are in C-9 condition. Any and all help would be greatly appreciated, thanks!
