For two years now, I've been drooling over a Mohr-Siebeck title: Paul Treblico, The Early Christians in Ephesus from Paul to Ignatius. It was published in 2005 and sold for like $250 as I recall.
It is out of print now (they must've only printed five copies) and unavailable. A search of Mohr's website only finds a few paragraphs from reviews of the book, but no listing. RBL reviewed the book as well.
For about a year, I've been lamenting that I was never able to purchase the book. Today, however, I was browsing Eerdmans' upcoming releases in preparation for my annual SBL book-buying spree and noticed that they've got the book slated for publication in October (just previous to SBL!) at a price of $85! That means mortals like me could actually purchase the book at SBL and probably get a decent discount.
This was encouraging in light of my recent disappointment with Royse's Scribal Habits book ...
