Head on over to www.halloweeenmovies.com, and go to their forums. They have one forum called "memorbilia" or something like that for trading and stuff. There is a guy named "Franchise" who has a bunch of Halloween rare cuts that he "trades" for about $15-$20. These include the tv/alternate cut of Halloween II, Halloween: H20, Halloween Ressurection (i.e., Halloween: Homecoming). I think he has a few more. Anyway, I love to get my hand on some of these cuts...been thinking about it for awhile. But you should definitely shoot him a PM over there...
