I've got almost all of those - when I first discovered Numan in 1995, the Beggar's Banquet double-album releases were all you could get. They were issued following "The Best of Gary Numan" double CD in 1993.
Berserker, The Fury, Strange Charm, Machine & Soul and Sacrifice were all reissued as part of the Numa Years box set in 1998, followed by repackaged versions of the albums. The following year, Machine & Soul, Skin Mechanic Live and Outland were all reissued.
A few years after that, his pre-Berserker albums were finally released as single CD issues, replacing the '93 Beggars double albums.
Ignore the compilations - during harder times, Numan allowed everyone and their dog access to the stuff on the Numa label, so lots of unofficial compilations with awful artwork hit the shops.
