I use Brisbet. Originally signed up for the free $100 with your first $100 deposit...figured it was a no-lose bet on the Kentucky Derby. I have had no problems with them.

Advantages: free past performances as long as you make a wager on the card you download (and it can be a $2 wager). they also have easy deposit/withdrawal which gets money into your account quickly and out into your bank account within a couple of days. Once in a while they offer rebate days if you bet a certain track...i.e. on Pimlico day, because they couldn't offer it, they gave a rebate on all dollars wagered on CD. And sure enough, the money was there the next morning.

Disadvantages: I think the video is poor, but I only have dial-up modem, so that could be the reason. I don't even view the races.

All in all, to get a bet down when you can't be at the track, I am satisfied with Brisbet.
