To be honest I don't think I have bought a new pressing (excluding Japanese ones) that wasn't a real disappointment, and that was in spite of paying £20 or more for them while the corresponding Cd's would be about £7. I even bought one (Third, Portishead) that had fingerprints *in* the vinyl!
It's not usually the sound quality, records tend to be cut by the few craftsmen left. It's clicks pops and general noise, just simple poor handling by people who patently don't know what they are doing. You accept pressings that you would certainly have rejected in the 70's and 80's because that's all there is.
I end up buying most Lp's on eBay, obviously not anything new that way. For instance I now have the complete back catalogue of Roxy Music and Bryan Ferry that I never had the first time around :-)
Of course it's a risky proposition they are often not as 'mint' as they are claimed to be, I now have three original copies of the wonderful Shirley Bassey (before you get any funny ideas this particular album has some absolutely cracking tracks) all look fine but are totally worn out and mistracked having been played on early 60's Dansettes, and I can't seem to get a decent copy of Pink Floyd's Wish you were here to save my life.
But oh, when you get a good copy of something, the sheer quality, involvement, space and imaging will take your breath away. I'm sorry, I'm a dinosaur, I don't download, digital leaves me cold (even though I will use CD because I have to) for sheer *communication* for that moment when your breath catches and you forget where you are *nothing* beats dragging a diamond through a wiggly groove.
