Have you checked out the publications available from Sandia National Labs? They have some good stuff that is neither too technical nor whacko. Not terribly current, but it should give you a good start.
And it's already been paid for with your tax dollars.

Grab the “Publications” menu and you can download a list of the available docs. I have hard copies, but I think they are all available on the web these days.
GOOD LUCK!
