3. Pretty sure here's only one rip
4. I remember that he had to redo it because people complained about the massive filtering.

Rip by JonandBT
I'd bet that some of the tapes are not worth the money anymore. A few years ago someone attempted a re-rip and it sounded absolutely horrible, so depending on how they were stored and the overall quality of the tapes some might be in bad condition. And that's not getting any better as they continue aging.
That's something that would matter to me if I paid that much money for it.
On a side note, I think it would be super interesting if you do a page or article on LPC, what the rarest items are.
Since you have a pretty good overview how many of each are out there, as an indicator.
I'd really like to see that.
