Psychobilly/Rockabilly?

(I apologize if this isn't in the correct board, or if I have missed a thread already made about it.)

So, this past November when I saw Rob Zombie, one of his opening acts was Nekromantix. I had never heard of them before, but I was hooked immediately. Their sound is just so BA. Well when I started doing a bit of a search on them, I discovered they were considered rockabilly/psychobilly.

My question is - Is anyone else into this genre? Or have you at least heard of it? I've been wanting to look more into it, but I just don't know where to start. If anyone has a recommendation, I would GREATLY appreciate it. But that isn't what this thread is about. I just mainly want to know what the rest of you think of it.

Opinions? Thoughts?
