I have most of the KISS collection on vinyl.
My highlights are:
The Originals - A rare re-packaging of the first three albums meant to boost sales after Destroyer was released.
They did this instead of a greatest hits.
and
Music From "The Elder" - a concept album that was the soundtrack for a movie that never got made.
It took me a long time to find that in a local second hand record store. Picked it up for $20 in mint condition.
