I count 959 iStripper model names
This is from the names.xml file in the data folder
I removed the "B" series of cards and all of the Beta Test Cards and the iDancer cards
so it is just series "a", "c", "d", "e", and "f"
I imported the names.xml in to excel
then did a Filter of Unique Values on the Models names
To further filter the DUO cards, here is a Formula I used
it filters to the 2nd Models name in a DUO card
=IF(IFERROR(SEARCH("&",B1),FALSE),RIGHT(B1,LEN(B1)-(SEARCH("&",B1)+1)),B1)
Then Apply the Unique Filter a 2nd time and you end up with 959 names
