A good link about editors

Kris Rusch has a good post on editors--what kind you actually need, what kind you can probably replace with insightful beta readers. I've done a couple of posts on the subject, too. She talks about having a proofreader go over your layout after a copy editor goes over your manuscript--I've done fairly well by laying out my book first and then having a single person do both jobs at once. Saves money, anyway.
