Montag Press
These guys seem to be hit-and-miss. When I got a book offer from them last year, I checked them out and emailed some of the authors, most of whom were pretty happy with the services rendered (though they said it was what you'd expect from a small publishing house.) So certainly they had some happy clients. But another person said she'd received many complaints from other writers about how they would hold manuscripts hostage and force authors to pay high rates to get out of binding contracts.
Well, I signed the contract and was introduced to one of their editors, who assured me how excited he was to start working on the project "as soon as I'm finished with these other three books I'm editing." In the meantime, he suggested I look through the manuscript and made sure it was in as perfect form as it could be before he took a look at it.
That was a year ago. I have literally not heard a word from him since. I haven't attempted to contact him, because I'm not interested in working with an agent who's either forgotten about my book or is just himself waiting for me to do his editing work for him. My book is locked up with them for the next ten years, but I'm not super crushed about that--I couldn't get any other agents interested in it anyway.
But they're very suspect. Avoid them.
