None, I refuse!
I made a point of buying all original U.K. LPs (yes, they are all out there) and for what people have paid for the 2012 Stereo LP set, and now the 2014 Mono LP box set, you too can own a pretty decent box set of original U.K. LPs.
Thankfully I sold my 2012 stereo box set for more than I paid for it and kept the black box to put my Original LPs in. Only downfall is I don't have all the Singles from the Past Masters.
Hence my new mission is now buying the Original U.K. Parlophone/Apple singles (45s)
P.S. On a side note HMV in Canada is selling the 2014 LP mono box set for $299.00 (coming down in price)
