For A rated books, take them. They will treat you fairly. If you want a bonus from a B (or even risk a C book), you can make your life MUCH easier. Before you deposit, email the book's customer service. Confirm the amount and rollover on the bonus. Be sure to include the name you will deposit under, and the amount you intend to deposit.
If there is a problem, it will usually appear before you deposit. "Your site doesn't say there is a $250 limit" or "What do you mean I need 20x rollover now?" are things this will avoid. If there is a problem later, you have a clear record of what exactly you received.
If you are a professional player, I recommend you also state the following in your email:
"Dear sportsbook:
I am a professional player. Can we agree that if you later decide you do not like my action that 1. I will keep a pro-rated portion of the bonus based on rollover I have met, and 2. My balance will be paid immediately to Neteller (or payment of your choice).
Most books either don't care, or don't understand when a player identifies himself as a professional. If they agree, you won't go through a hassle getting your money or bonus when done. If they don't want you, there are plenty of other places that do.
