I usually end up keeping 1 out of 5 those albums. I clean them, with a VPI vacuum cleaner, put them in a new sleeve, etc. But, overall, am I a slob? Yes. Do I have $30+ for an album? No.
I absolutely love to find these gems, with notes on the album, sometimes a signature, receipt from 1972. This is why I stick to vinyl, I want to listen to music made in 1972 on a medium from 1972.
