Very curious what your DVD collection entails. Movie lovers come and go from these forums too much, and I do definitely enjoy reading a majority of your posts.
I just hit 886 DVD's, and a good majority ~350+ are all horror. It's definitely my forte. Horror is my life, and I usually try to attend several horror conventions annually. I actually just went to Days of the Dead Chicago last month which was small, but still pretty cool.
If you haven't already, I suggest making a DVDaf account. It's a real nice site that I've been using for nearly six years. It allows you to log all your DVD's into an online collection. Pretty neat.
