Almost all the major sites do. Most won't have them up yet, but they will definitely be up in April. Two sites, in the Sticky thread at the top of this forum, are:
www.sportsbookpal.com
www.sportsbookreview.com
Like I said, most sites take these bets. The key is getting the best lines (like with everything else), but it is especially important here, because your money is tied up for much longer, so you want a higher return.
