There're bootleg vinyl and CD copies - the vinyl is relatively easy to find, but not for cheap. I've only ever seen one version of the CD bootleg and that went for damn near £200 (!) and as for the cassette original... yeah, NEVER going to happen hahaha. Probably the single most sought after Coroner release in existence.
I actually quite like the Pray for the Sentencing reissue. the remaster of Pray on that release ounds absolutely incredible, far better than the original, and the slight remix that the first album got was great too, though I too would rather own the originals hahaha
