I'm a total film geek when it comes to obscure movies, but when it comes to finding really obscure stuff I find it better to trade than actually pay the ungodly amounts I find on e-bay and other sites.
I only deal in "public domain" and unreleased films for trade, but I have quite a collection to suit just about any taste. I prefer trading in VHS format, but I can make DVD-R if needed. My mailing address is:
P. O. Box 501113
Tulsa, OK. 74150-1113
I've had the same address for nearly 20 years, and it won't change anytime soon. Feel free to hit me up with lists of what you have and I'll do the same.
