A little late, I know...(watching the episodes in reverse)
I found the NXP packaging cheat sheet quite handy, but obviously it just covers SMD parts. Is there also a THT sheet available? I know the standard TO-3/5/18/66 cans and the usual TO-92/126/220 transistor packages, but I always have to look up cans with a different number of pins (like TO-72), diode packages like DO-5/201, larger non-DIP ICs like TO-200, smaller (bigger) transistors like TO-237 (TO-247/264) and also wattage of resistors is up for guesses unless stated on the body. So a reference sheet for those would be nice, too...
