I've actually been wanting to buy Tricks of the Mind, I'm sure it is amazing. One of my most prized possessions is my copy of Pure Effect.
I understand that you are looking for books on Mentalism, and Pure Effect doesn't focus strictly on mentalism, but on performance technique and philosophy to help refine your showmanship. In my opinion the advice goes unmatched to anything else I have read on the subject and truly helped me become a better performer. It has a small slew of effects in the book but this is not the main focus, and as I understand that is how Tricks of the Mind is set up. Absolute Magic has no effects in it and is all on performance and showmanship and I am currently reading that and it is as good as Pure Effect.
Overall, D.Brown's work is amazing (and he is an extremely good writer as well), and his past literature has been of astounding help to me so I would assume Tricks of the Mind would meet the standard that he has set for himself. I'll be buying a copy soon and I'll let you know what I think.
As for other products - Ian Rowland's Full Facts Book of Cold Reading, Banacheck's Psychological Subtleties 1 & 2 (and lots of his other work), Daniel Madison's IDENTITY, and check out Jay Sankey as well.
Hope this helps
