Aric, they're right. Whenever a Hank LP goes on eBay, some Japanese high roller puts in a $2000 bid that drowns out all other bids.
I think the price the BN LPs go for is utterly ridiculous. I was around when they were readily available, and they were great of course, but we didn't worship the things. There are many other labels, such as Impulse, that are just as good. For some reason, you can pick up Impulses in fine condition on eBay for no more than $20, usually less.
I'd settle for good CDs, such as TOCJs, and let the anguish go. I have all the Hanks on TOCJ if you need any copies.
