I also have a pretty big wishlist of books I would love to include if I had them, such as the TDNT or the Dictionary of Deities and Demons.
I've got one of those too; the problem is that a lot of religious books are low production, so they cost more... like I'm looking at a bible commentary that comes from the University of Navarre in Spain that costs over 200$ US. Needless to say, I need to get a job.
