The 1989 Varèse Sarabande album was a top
collectible from 1992 to 2003. Only 1,500 copies were printed through
the Varèse CD Club and it originally sold through the label's
mail-order service for only $12. At its height in the late 1990's, it
sold for as much as $2,500.
The 2004 Prometheus album is not one of
their limited club titles, but was still mostly available through
soundtrack specialty outlets. For a long time, it retained a value
under $20. That price point was where the 2011 Intrada album started,
though that product is limited to only 1,500 copies and targeted at
the specialty outlets.
