I'll just mention for anyone seeing this, that I do need tapes #36-100, plus collector's series before #49. But owing to a medical situation of my own, they'd have to be pretty inexpensive, and I doubt anyone would ever sell them for what I can pay. The tapes I have cost me $200, which was astronomical for me, but it amounted to $1.50 apiece (at a thrift store). They don't have to quite that low... maybe...
