Look up top, many good ones. Olympic, Carib, CRIS, VIPSPORTS, Pinnacle, etc.
I don't like Sportsinteraction since they screwed me.
There's one I've tried to get into that's up there, it's called ASK MADJACK, but when I click on it, it only opens my email thingy.
But seriously, depending on what and how you play, send Madjack an email with your types of bets, limits, sports most wagered on, types of bets (props, half times, totals, etc.) and he'll probably let you know about several that fit the bill.
