I've just moved to Canada from the UK and can't beleive how bad the sport books are here. I do all my betting with betfair.com - its a betting exchange which means you're betting against other customers rather than the bookie. The juice for most games because of the number of customers is normally about 1% by the time of the game and for horses its about 2-3%. I'm no betting guru but I know value when I see it! Hope it helps you guys out.
