Miles Davis "Workin" Analogue Prestige Releases

I am in search of a high quality original analogue master release. Does anyone know of a specific release over the last decade or so? I am trying to obtain a copy without paying hundreds of dollars on Discogs for 1960s pressings. Also, does anyone know how the mid 1970s Japanese releases sound? If anyone has direct listening experience please respond.  Thanks everyone.
