MX Publishing out of the UK?
They have about a dozen or so authors at the moment, so they're not huge. Their books can be found on Amazon (.uk, com, and .ca) as well as in Borders and other good bookstores.
They claim to be in between a self publishing house and a full publishing house, somewhere in the middle, however they choose the titles they publish and have a few books that are doing quite well. They do charge a fee of 150 Pounds to launch the book to the US and UK markets, and they also pay 10% royalties. I have checked stock availability on a couple of titles, and Borders does seem to stock them.
Would love your comments / thoughts / opinions, as I am considering entering into a contract with them.
