Print On Demand Question

Does anyone have any recommendations, experiences, or other comments about Print on Demand companies? My history of the Albion Fire Department can't go through traditional publishers, because the subject matter is too narrow. (Which I don't understand, because hey -- what person in, say, Rome or Moscow wouldn't want to read about small town Indiana history?)

I thought I'd decided on which POD company I wanted to use, but now I'm not so certain. I need one that can handle some of the setup chores that are beyond me (Emily can handle a lot of computer type stuff, but I don't want to overwork her). However -- and this might come as a shock -- I don't want to get taken to the cleaners, and the budget is limited. Suggestions?
