Fujita,
There are actually many companies out there that offer more and some less of the amount.
A main issue with online casinos or lotteries is how long the are established and can you trust them. It does not help you to win $1000 for a straight hit when you will never see the money.
You are a bit dependent on the people that dealt with the online companies before to not get burned.
Besides CaribSports (interesting particularly because of the PICK 3 gaming option) I also like PlusLotto. They do not do PICK 3, but they have a cool 5/15 lottery every hour, which I personally like, it allows to test PICK 5 systems to be tested without having to wait a week or half a week for the next drawing.
But whenever you play offshore or in an other country, you always have to aks yourself: "Who and/or what am I supporting?". The discussion recently came up under a different topic. State lotteries ar trying to gather money for education and other important areas.
Good Luck
