Yeah, Amazon's pricing algorithm will drop prices sometimes if no-one buys an item for a while, can result in erroneously low prices sometimes, after which it pops back to list. I periodically check prices and have gotten some very good deals, especially on Tacet.
I believe there were a lot of them made, 'cause seems like with a little patience you can find them at a decent price (except that Scheiner one perhaps!)$28? I might think it's low....but I really don't know. I keep holding on to my copy thinking it's worth something. Maybe it isn't.....
I second the question.
Three excellent questions. DTS-HDI third the question.
