How do you choose a sportsbook?

It's a frequently asked question… The answer often comes from the websites who offer betting services and make money on it. They write about their own benefits first; then cut their names off the text and the 'choose a sportsbook' article is done :-)

Well I am not that interested in this or that sportsbook revenue, so I'd better share my opinion on what I consider most important when choosing a sportsbook. Feel free to correct me or add anything I've happened to omit.
