Now that I recall, I did try a Zelazny book (I don't remember which one) a long time ago and couldn't get into it. I've heard of "Neverwhere" and was intrigued about it; you're recommendation is enough that I think I'll give it a try. A lot of the other authors I never heard of but will definitely check out (with many thanks!). I'll also check out the first few pages of the thread as you suggested (just didn't want to slog through all 24!) I guess we can agree to disagree about whether horror should be a separate genre or not. I do agree that elements of horror can and do exist within the fantasy genre (or even that some established horror writers can make successful forays into Fantasy or Science Fiction for that matter). Further than that I'm not willing to go.
Please don't get me wrong, I really do appreciate your feedback.
