I have to say, I really like my Deardorff. What makes a Deardorff for me is the 1 inch (or, a little more?) up/down adjustment on the front standard. Plus, they're a beautiful camera.
I think that the trick in purchasing a Deardorff is finding one that has tight adjustments. Mine's about a 1948 or '49 camera that was in nearly new condition when I purchased it a few years ago. With new parts that are available at that auction site, I added front swing, and I have parts to upgrade the lensboard holder.
With that said, watch the dealer that sells these new parts. Purchase only through the auction site, so that you have some clout in getting them shipped within a reasonable period of time.
