so i've read the whole "in search of the dark side holy grail" thread and just got more confused. of the more common releases of Dark Side of the Moon, which should i buy? i'm hoping it will be one of these three Black cover with words blue, sacd 30 year import? or maybe a different version, but can find at best buy or amazon i don't have an sacd player. PLEASE DO NOT MAKE THIS A HUGE THREAD!!!
