Assuming you consider Victor Martinez a part-time catcher, part-time first baseman, and part-time designated hitter, John Buck was the best free agent catcher available this offseason. He hit .281/.314/.489 with 20 homers for the Blue Jays last year, but he's since signed a hefty three-year deal with the Marlins. As always, the number of teams looking for a quality backstop far exceed the number that are actually available, but there's still a few out there.
Miguel Olivo is a lock for double-digit homers year in and year out, and the same can be said for Rod Barajas. Both have thrown out a high percentage of would-be base stealers historically. Yorvit Torrealba has a .346 OBP over the last two years, a mark just eight other catchers can top. Jason Varitek hit for a ton of power (.473 SLG) in limited action this year. Then there's A.J. Pierzynski. He's started no fewer than 124 games behind the plate in five of the last six years, and his .284 AVG since 2008 can be topped by only three other catchers.
The Dodgers, Rangers, and Padres are known to be seeking help behind the plate, and it's safe to assume that the Mariners and Red Sox will hunt for upgrades as well. It wouldn't be a surprise if the Yankees, Rockies, Mets, or Orioles tried to improve their backup catcher situation either.
