I'm delighted with BookBaby.
The people know what they're doing. They are personable and responsive ... quickly. They follow through. They have systems in place that tell them what happened at each step of the way. When I upload a file, several people are aware and depending on their role, they quickly respond. Plus many systems are automated so there is a system intelligence that has a structure and timely agenda. And finally, the quality of print output is outstanding. Hopefully, the eBook quality will prove to be so, also....
