As for updates from CQ: I have two books coming out with them, the first in November. I connected with them through the Pitcharama contest held over at
http://aussieownedandread.com/ . The acquisitions editor was great and very enthusiastic. The editing was very thorough for one of my books (the other book was already much further along as far as development and polish, so it didn't require as much work). For both books, they have been timely and professional, answering all questions promptly. Small publishers aren't for everyone, and there are some serious considerations. I recommend listening to this podcast (
http://www.shippingandhandlingpodcast.com/post/122200709847/episode-17-summer-reading ) since someone asks about small publishers specifically (around the 40 minute mark, so there's quite a bit of chat leading up to the question). They talk about some of the hurdles that go into publishing, and trying to advance in publishing after taking a swing with a small publisher.
So, in short: I've thus far only had good experiences with them, but I'm also not all the way through the pipe and at the point of trying to sell my books to readers yet.
