Powerman 5000's Anyone For Doomsday? was limited release and then pulled/scrapped by the band, and they went another direction musically. I really liked the album, though. 5-10 years ago they were between 200 and 400 dollars for a real copy on ebay. A quick look at amazon confirms its still bat**** expensive, 200 used, 360 new.

When I was 15 I almost spent all my savings on a copy. It is probably their strongest work. Alas, I don't actually own it, but it is very rare...
