Task prompt: Persona: I'm throwing a birthday party for a friend here in Billings in two weeks and I want to get them something special. They collect mostly rock vinyl records, which is great. I love vinyl and I love rock. The problem is: She pretty much has all of the rock records she wants. I'm talking about the Doors, Led Zeppelin, Pink Floyd, etc. So all she's looking for are rare, hard to find, original psychedelic rock LP's from the sixties. The kind that were never in the Billboard Top 40 or even Top 100 and that really only collectors know about. The kind that sit high on the "show off" wall because they're so amazingly cool, rare, and expensive. The kind that my friend drools over.  Apparently, she tells me, some were pressed by the bands themselves in runs of 1,000 or even 100 or less, which makes them very rare!  Though I'm into rock, I really don't know the first thing about how to find these "grails" and I don't want to get her something that will disappoint. Can you recommend some records that she'll love? I know these records are expensive because they're so rare. When it comes to condition, they need to be nice. 

Prompt: Recommend four rare original psychedelic rock records from the sixties that cost between $600 and $800 each. Please include one that was pressed in a run of 1000 or less. They must be available to purchase in the US.  Provide links.  Please explicitly state whether each of your product recommendations meets each of the product requirements that I want. Include the source or purchase links, and prices if applicable.
