What i do, and this is just me, each to thier own, is go for Vinyl and CD format. If i really like a track i will try to get it on vinyl. However i will also "bulk buy" tracks ,if you like, on CD to pick up tracks that i like but not enough to outlay say £20-30 but then have the track and a number of others to go with it. Building a healthy collection of sound this way.
Drawback is the temptation to then collect all one artists tracks on vinyl.
Dont go for MP3 that much.
Oh and i prefer originals but have no problem with re-issues.
This is a change in attitude for me as at one point i was a CD only buyer, one positive effect from soul source.
Thanks chaps You do get a buzz from holding the big black penny. Had forgotten though.
