You might want to check out a recent method developed in our group,
called "Minimum Probability Flow Learning" that allows very fast  
estimation of basically any distribution -- including the Ising model.
A 100 unit ising model can be fitted within about 1 minute (see Fig. 3).
The paper is here: http://arxiv.org/abs/0906.4779
