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+).
They are out there. I bought two beautiful raw copies out of OO collections over the past 10 years. One slabbed out 9.8 white and the other in my collection is 9.4/9.6.
Still haven't found a 9.4+ Tomahawk 116 though. Now that's a tough Adams book in true NM or better.
Kept this one since the 9.8 had a miswrap.
Drool worthy.
