I don't know if any of you follow such things but bookfinder.com, which searches every used book on the planet, only finds three copies of the Moser/Vernon/Paul guide to Needles. Maybe it's only two copies.
I've never been to Needles and my copy of the guide looks like it has never been opened.
If this is the book Munge refers to, yes the book rates Love Potion #9 as a 5.10 "five-star classic."
I used to exchange info with Sally Moser but I haven't heard from her in years. She was director of the Access Fund for awhile - I bet that didn't pay much.
By the way, I'd happily let my copy go for something less than $4632.03.
