I don't collect the toys quite as much as I watch the show, but I've been working on a Power Rangers toy spreadsheet for sometime now out of shear boredom. Its based mostly on what info I could find floating out there on Power Ranger fan websites and ebay (toy name, toy line, price, item #, asst. #, etc.) combined with my notes on possible toy/packaging variations, unreleased prototypes, foreign/store exclusives, comparisons of the show to the toys (such as characters having different names on the show from their toys, characters not appearing on the show, or characters coming from unused footage that appears in the Japanese source footage, but was not used in Power Rangers, etc.) and the like.
This is EXACTLY what I am looking for! You have my IM so IM me when you can.
