pin sizes for extractor and crimpers? recommendations?

Yes, I cross posted this to RGVAC, but it fits here too. Any help/advice appreciated. What are the sizes of the pins used in typical Williams, Gottlieb, etc. games? .156, .093, .062, .165, other? What pin extractor tools and crimpers do you use that you like/dislike? Is the "spring loaded" extractor worth the few extra bucks? I've found a lot of places to buy them on the net, but if anyone knows any place that has some great prices on them, please let me know. Seems like spring loaded extractor tools are about $12, and crimpers $20-30. Thanks, Joe joemagiera@ameritech.net
