I've got a few sites that I regularly check when looking for new kindle books, and I'm searching for a few more. I'll show you mine if you show me yours. What do you say?
http://journalofalways.blogspot.com/ -- This is an excellent reviewing site run by a guy who proves time and again to be a very perceptive reader as well as a very open mind. Definitely worth the follow...not just the blog but his reading list.

Then these last two are book listings, the first is anything under $9 and then second is focused on young adult books (one of my favorite genres) for kindle. I find a lot of my reading list here.
You know of any others you recommend? Where are you hearing about your new books?
