If you go to
progarchives.co.uk: The Leading Prog Archive Site on the Net and check the ads, I'm pretty sure there are some very solid shops there that specialise in prog rock on vinyl, and though I don't know the prices I think they're all music heads so would not be about to rip you off.
Worth a shot?
What's an RP1 by the way? I assume some top-of-the-range stereo equipment? Turntable? (The kids stare blankly...)
