I can only say what ive paid for the Daphne Descends and True Power.
I think i paid around 225 $ for the Daphne Descends, and the True Power with cue sheet, i paid 200$.
I owned a copy of True power without the cue sheet which i paid 150$ for, i guess thats the one i sold to you a while back for less what ive paid for it if i remember right.
Lotta ppl love collcting French stuff, which makes it worth more and more sought after i believe, since its rare and pretty special.
Maybe one reason its more sought after then True Power.
