Bovada (Bodog) has Arena lines up now. So does Jazz, Heritage, 5 Dimes, SBG, BOL and Sportbet. In Vegas, Southpoint has posted lines to go along with William Hill. This is actually a promising sign -- I was worried that we wouldn't see any lines at all.
LA (#103) is worthy of a wager down to +4, IMHO. Currently, most books are priced either +6.5 or +7....
