why would you be interested in betting puck lines for? They are the biggest ripoff of all time.
It's very very rare that you find any value in a puck line.. The only time you usually find value in puck lines is when the line is -0.5 pick em.. You will have to get either an ev-0.5 or a 0.5-1, which will no matter what give you 10 cents off no matter what.. But then again, the book that carries a puck line, will be smart to not put up a puck line in this situation and give you a flat pick em a -0.5 pick, laying 10 cents on both sides. So don't even bother with the puck lines. yes you might find value in them, but boy, is it rare. Not worth the effort.
But to answer your question. here are some books..
SBG Global
Olympic
WWTS (but these crooks charge vig on the puck line LOL LOL) stay away from any book that charges vig on a puck line. You should be playing vig free on the puck line (aka. split line)
Good luck to you..
