Church AUssie Remasters....

anybody drop $25 US on these recent remastered gems from the classic Church period...are they a substantial improvement the originals?
i'm on my 3rd round of these titles, and yes they are worth it for the extras alone...the audio is better than the older cd releases, but not dramatically so...if you're a fan you'll need them all,if not,start with the blurred crusade.
