Thanks to all this RL hype, a decent copy will now be $1500? Stamper guy has sharpened his writing skills since 2015. Now he can REALLY sell the sizzle for that steak!
The last time I heard about any RL / SS pressings selling, they were $2,000+.
The price is based on sound quality and rarity.
Only 200,000 RL / SS pressings were made. That was 57 years ago.
Considering that teenagers were buying them, playing them to death, with misaligned and not good cartridges, and mishandling them, not too many survived in excellent condition.
"Stamper guy" (Tom Port) offers them for sale, when he finds one, which is, at most, one per year. And they are not always in high grade condition (and his grading is by ear -- how it sounds -- he plays them to grade them).
No one is being strong-armed. You have 30 days to return any purchase -- no questions asked.
No one has to pay his prices. Anyone is free to find one somewhere else.
