It sometimes makes me wonder if places like our forum contribute to the "problem" in some way, meaning, these pressing we often talk about aren't new to the public, they've been out there, it's just that "We" seem to band together and share our opinions on pressings, sometimes find a common thread (KG) and move forward on it. I say this because there have been a few KG pressing of 70's albums I've had on my list that mystically have gone way up in selling price over the last month or so.
I know we have a lot of lurkers, look at the 1 post Buy/Sell/Trade members that pop up now and again kind of projecting the idea of "Oooh, I have a captive, hungry, willing to pay whatever" group on my hands
