Well, it's certainly worth having just for collectible sake, but not really worth listening to in quad. There is a Japanese version of Atom Heart Mother in the RM format as well. I have it but not DSOTM (I have a CDR copy of it though). I still want an RM copy of DSOTM just to have in my collection, but I'm not willing to shell out more than $100.00 for a mint copy. Over $250.00 for one in "EX-" condition is absurd.
