Changeling Press (http://changelingpress.com/) also publishes some very nice M/M romance, including my Dark Callings (http://changelingpress.com/product.php?&upt=book&ubid=21) series. In spite of recent rumors, they're very much alive and well. And they're also very nice to work for, and even writing in a mid-selling genre with them, the royalties are decent--actually for e-pub they're damn good.

I'm a little weirded out by the "original slash" term, too, though I do get what it means and why it has come into usage. My own books came out of my love of writing slash fic, and I wanted to write something that gave me that same kind of emotional punch.

Thanks for the extensive info--I've been following this market, though rather casually, and the growth over the past couple of years has been both gratifying and fascinating.
