It's a tough book period. But, there are still a lot of BA collections out there, and by it's nature (even with the internet) it is a very personal and private affair.
This is the one book I have never found in 9.4+ in any DC/Batman centric collection I have picked up. The main Batman issues (227, 232, 234, 251, etc.) and Tec issues (395, 400) are easy to land in high grade, but the post-400 Tec books tend to be hit and miss condition wise in the collections. Tec #405 (1st League of Assassins) is another tough book in high grade (9.4+).
