SportsInteraction's bonus on $100 is second to none. If you only want to deposit around that amount, I say go for it. They have a ton of betting options and the live betting is very good. Just make sure to use the link above (or the one in my post) to sign-up to make us moderators look good. Much appreciated.
If you are planning to deposit much more than $100, let me know and I can steer you in the right direction. If it's around $100, that bonus is almost too good to let go by.
