Hello Josjac, the ones I know of, were already recommended to you (Fairlay and BetBTC).
Once you try them out I would like to ask you to leave a vote in my rankings thread. You can vote for other bookies as well.

Here is the Sports Book rankings thread
https://bitcointalk.org/index.php?topic=1820529.0

Fairlay is actually ranked 3rd there, with 17 votes, so you can also check for players reviews on the thread as well.

Good luck!
