I must say I kinda agree with janitorfrommars about this. "The Time is Nigh" is really haunting, less "parodic" than the double-live sets (PSF's, "Purple Trap" and "I Saw It!") or, say, Pathetique. Still, every piece is most enjoyable.
Now that's true it's hard to grab most of the Tokuma. I remember I had the chance to get "A Death Never to be Complete" for $20, but I had to chose (that day I bought "The Time is Nigh" and "The Wisdom Prepared" for the same price). In a few hours, there was nothing left.
Oh yes, and about the '96 "Purple Trap" double live (ltd to 500 copies on Blast First) : a copy was sold immediately on eBay for $150, four hours after the beginning of the auction. There was another one on amazon.fr, for $110, sold in a couple of days.
Maybe you have to become a hardcore record geek to find something - at least on the web
