Well both 1 and 2 can be good but again you will have to know which performances are and which not. If stereo is too expensive and mono is cheap you can take a punt, but in some cases like the Kogan Gilels the mono will also be 500 if you can find a good one. This is what the General knows, specific pressings, other wise just buying 33cx first presses might make you lose money
Well, I asked him but no reply. I prefer to PM or would love a private area for the forum but... here we are if neither or the ladder are happening.
It's a good thing that I really don't care about Kogan too much. Although funny enough you named the only one I'd probably want. The most lucky thing IMO with finding performances on the really old stuff is that YouTube if FULL of them. It helps me get an idea if I will like something or not. I just want to make sure I'm not buying garbage vinyl discs of good performances.
