I've been very happy with Brisbet. Wager on-line or by phone Sign-up during one of their promotional periods and get a free $100 if you bet $100 the first month. No fees. Free fund tranfers from your bank account. No minimum monthly betting required. Free streaming video if you bet a small amount monthly.
Customer service the best. One of their techs solved a small connection problem and went on to help me fix other things on my PC not even related to my account.
They cover all American tracks and some international racing as well.
