If you're interested in Medium Format photography, and you have web access (obviously you do), you need to get interested in the Medium Format Digest. Essentially, the Medium Format Digest is just a big question&answer forum for people who want to know more about these excellent cameras. Especially important is the immense amount of information available about older (ie - less expensive) cameras and how they rank compared to the newer (ie - arm and a leg) ones. If you're just getting started with MF, it's necessary info that you need to have so that you don't get burned.
