Just curious about this one. I found a rather short one (15 minutes record time) months back at a thrift store, disassembled it, and used the reels to make a little model reel to reel. Last week, I found two CRC-90 tapes at my Goodwill outlet with music recorded on them (one Earth, Wind, and Fire, One Stones) that sounded like they had been recorded from albums with surface noise. I paid 50 cents for the pair. Since I had learned they seem to flip for a fortune on eBay, I tried just that. The tapes are used and not with original cases or J-cards, and yet they are now nearly up to $40.00 with 3 days still to go. Not that I'll complain about that, but why? I had assumed they were some super high quality tapes, but from what I've read (and heard) these are not great quality tapes. Nonetheless sealed ones can go for upwards of $100.00 apiece. Is it really just the "cool" factor of the miniature reels? I can't deny they look pretty, but I just don't get it.
