Poll added: Which is your favourite army book?

Just for a little bit of statistical fun: which is your favorite army book(s) of those available here?
I have only included the "main" ones that can be used as stand-alone lists, and not the expansions. Feel free to pick several options if you want (but preferably no more than 3).

Edit: Apparently Blogspot have some issues when it comes to polls, making votes mysteriously disappear (as has been the case here already only 5 hours in!). I will be looking into replacing the current one with a better alternative.

Edit 2: New poll up and running! Never-closing, 3 answers max, no repeat voting - all better, in short! Sorry for the inconvenience, I hope you will take the extra 3 seconds required to vote again in the new poll ;)
