The OP's question stipulated the price for a single LP, not a boxset. Ignoring that stipulation if I may, my taste in music and the resulting LP's I have looked for has not required me to spend more than I care to for any single disc. But I HAVE spent much more for some of the great Mono boxsets that have come out in the recent past---The Beatles, Dylan, and some of the great boxsets that some of the UK (ACE) and German (Bear Family---fantastic!) companies put out in the 80's-90's, of 1950's Rockabilly, Rock 'n' Roll, Hillbilly, Bluegrass, R & B, and Blues artists. Money MUCH better spent than the audiophile reissues that sell for $30-$50 (and more) /disc.
I admit the Analog Productions reissues are really well done, and well worth their selling price. My dilemma is, do I REALLY need the AP version of Cat Steven's Tea For The Tillerman? The sound of my original UK Island (yeah, the pink label one) is astounding, and though the AP reissue may be even better, I don't like the music enough to care. My funds are not unlimited, and I'd rather spend the $50 on three or four LP's of new music.
