A copy with good corners, that has not had too much fade, is worth $50. From what I've seen, the paper used did not turn out to be great for longevity. I personally got a PDF before the Great PDF Purge, so I am lucky in that way. One option to consider is that you could probably assemble an actual BECM kit for about $7 per book if you are not picky about condition.
