i also have about 55 episodes of Head of the Class, i am looking to trade for more. i hope to one day be able to make a complete series set, or at least seaons 1 through 4. i am awaiting to hear back from someone on another site who claims to have alot of episodes and is converting some of them to dvd (he has some episodes i don't.), but in the meantime, looking for whatever i don't have.

thanks!

wow you have a lot of episode so head of the class. would love to get that complete myself. i got a 7-8 disc set off ioffer 5-6 years ago but episodes were all in some weird order and names they put on the disc didnt make any sense so i have to go through them and see what is on them
