I buy most of my 'music' in digital format these days, but had the desire to collect a few of the more influencual mixes in the original format.
Most mixes are in some ways 'disposable' to me, but that one, along with the Terry Francis 'Architecture' CDs and a Kevin Saunders X-Mix one (next on my list) I would like the 'originals'...
No major, just like how some guys decide to hunt out some obscure first pressing of a tune, rather than the new, better mastered and pressed re-issue...
